Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Group Temporal Key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). A group key reload vulnerability exists in WPA2 wireless network sleep mode. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The WPA2 wireless network re-installs the tunnel in the TDLS handshake. The TPK key vulnerability exists when the PeerKey is set up directly. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). There is an IGTK group key reloading vulnerability in the fourth handshake of the WPA2 wireless network. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. Those vulnerabilities applies to both the access point (implemented in hostapd) and the station (implemented in wpa_supplicant). An attacker exploiting the vulnerabilities could force the vulnerable system to reuse cryptographic session keys, enabling a range of cryptographic attacks against the ciphers used in WPA1 and WPA2. For the stable distribution (stretch), these problems have been fixed in version 2:2.4-1+deb9u1. For the testing distribution (buster), these problems have been fixed in version 2:2.4-1.1. For the unstable distribution (sid), these problems have been fixed in version 2:2.4-1.1. We recommend that you upgrade your wpa packages. ========================================================================== Ubuntu Security Notice USN-3455-1 October 16, 2017 wpa vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in wpa_supplicant.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11r allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the fast BSS transmission (FT) handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. Wi-Fi Protected Access (WPA, more commonly WPA2) handshake traffic can be manipulated to induce nonce and session key reuse, resulting in key reinstallation by a wireless access point (AP) or client. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The PTK-TK encryption key reloading vulnerability exists when the WPA2 wireless network receives and processes the retransmitted fast BSS transition reassociation request. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The IGTK group key reloading vulnerability exists in the WPA2 wireless network. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. Those vulnerabilities applies to both the access point (implemented in hostapd) and the station (implemented in wpa_supplicant). An attacker exploiting the vulnerabilities could force the vulnerable system to reuse cryptographic session keys, enabling a range of cryptographic attacks against the ciphers used in WPA1 and WPA2. For the stable distribution (stretch), these problems have been fixed in version 2:2.4-1+deb9u1. For the testing distribution (buster), these problems have been fixed in version 2:2.4-1.1. For the unstable distribution (sid), these problems have been fixed in version 2:2.4-1.1. We recommend that you upgrade your wpa packages. ========================================================================== Ubuntu Security Notice USN-3455-1 October 16, 2017 wpa vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in wpa_supplicant.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the four-way handshake, allowing an attacker within radio range to replay frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The WPA2 wireless network has a GTK group key reload vulnerability in the fourth handshake. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart the Wi-Fi network interfaces/hostapd or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart the Wi-Fi network interfaces/hostapd or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The WPA2 wireless network has a PTK-TK key reload vulnerability in the fourth handshake. WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.

Revision history v1.0 2017-10-17 Initial release. v1.1 2017-10-19 Add patches for 10.x releases. I. hostapd and wpa_supplicant are implementations of user space daemon for access points and wireless client that implements the WPA2 protocol. II. Problem Description A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. III. Impact Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used. IV. Workaround An updated version of wpa_supplicant is available in the FreeBSD Ports Collection. Install version 2.6_2 or later of the security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf to use the new binary: wpa_supplicant_program="/usr/local/sbin/wpa_supplicant" and restart networking. An updated version of hostapd is available in the FreeBSD Ports Collection. Install version 2.6_1 or later of the net/hostapd port/pkg. Once installed, update /etc/rc.conf to use the new binary: hostapd_program="/usr/local/sbin/hostapd" and restart hostapd. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date.

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). WPA2 is prone to multiple security weaknesses. Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: wpa_supplicant security update Advisory ID: RHSA-2017:2907-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2907 Issue date: 2017-10-17 CVE Names: CVE-2017-13077 CVE-2017-13078 CVE-2017-13080 CVE-2017-13082 CVE-2017-13086 CVE-2017-13087 CVE-2017-13088 ===================================================================== 1.
