TITLE

glibc vulnerable to stack buffer overflow in DNS resolver

DESCRIPTION

Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. GNU glibc is an open source C language compiler released under the LGPL license agreement. It is an implementation of the C library in the Linux operating system. An attacker can use the vulnerability to launch an attack on a Linux host or related devices by constructing a malicious DNS service or using a man-in-the-middle attack, which results in remote code execution and can be obtained.

Description: The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. (CVE-2015-7547) This issue was discovered by the Google Security Team and Red Hat. All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.

Release Date: 2016-02-18 Last Updated: 2016-02-18 Potential Security Impact: Remote Arbitrary Code Execution Source: Hewlett Packard Enterprise, Product Security Response Team VULNERABILITY SUMMARY A security vulnerability in glibc has been addressed with HPE Helion Eucalyptus Node Controller and other Helion Eucalyptus components. The vulnerability could be exploited remotely resulting in arbitrary execution of code. - Helion Eucalyptus Node Controller (NC) components are confirmed to be affected by the vulnerability. Other Helion Eucalyptus components and pre-bundled service EMIs do not directly expose the vulnerability, but because glibc is a commonly used library on Linux, the exact exposure is hard to determine. Any software performing domain name resolution is potentially vulnerable. References: - CVE-2015-7547 - PSRT110035 SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed. - HPE Helion Eucalyptus 4.2.1 and earlier - HPE Helion Eucalyptus Service EMIs for Load Balancing and Imaging services package "eucalyptus-service-image-1.48-0.87.99" and earlier BACKGROUND CVSS 2.0 Base Metrics =========================================================== Reference Base Vector Base Score CVE-2015-7547 (AV:N/AC:H/Au:N/C:N/I:C/A:P) 6.1 =========================================================== Information on CVSS is documented in HP Customer Notice: HPSN-2008-002 RESOLUTION HPE has made the following software updates and workaround information available to resolve the vulnerability with glibc for HPE Helion Eucalyptus. + All hosts running HPE Helion Eucalyptus services should be upgraded to the latest glibc. Updated glibc packages are available for RHEL and CentOS: https://access.redhat.com/articles/2161461 **RHEL Note:** After following the guidelines for RHEL, a reboot is the safest and recommended way to ensure that updates takes effect for all services. + New Helion Eucalyptus Service EMIs will be made available soon in the Eucalyptus software repositories at: http://downloads.eucalyptus.com/software/eucalyptus/4.2/ **Note:** This security bulletin will be revised when those updates are available. Until Helion Eucalyptus EMI updates are available, the following workaround is available to update the instances launched from eucalyptus-service-image-1.48-0.87.99 and earlier to the latest glibc packages. **Workaround:** As a cloud administrator: 1) create an update-glibc script with the following content: #! /bin/bash yum update -y glibc 2) set the following cloud properties to use that script on instance start: euctl services.imaging.worker.init_script=@update-glibc euctl services.loadbalancing.worker.init_script=@update-glibc This script will be automatically executed for each of the new instances started from the service image. For instances that are already running, the cloud administrator will need to terminate them and start again for the script to take effect. More specifically, for the Load Balancing service, the cloud admin needs to find all instances running under the "(eucalyptus)loadbalancing" account: # euare-accountlist | grep loadbalancing (eucalyptus)loadbalancing <accnt_id> # euca-describe-instances verbose | grep <accnt_id> And terminate them using euca-terminate-instances. New updated instances will be started automatically after that. For the Imaging Service, the imaging worker needs to be terminated and started again: # esi-manage-stack -a delete imaging # esi-manage-stack -a create imaging HISTORY Version:1 (rev.1) - 17 February 2016 Initial release Third Party Security Patches: Third party security patches that are to be installed on systems running Hewlett Packard Enterprise (HPE) software products should be applied in accordance with the customer's patch management policy.

Cisco Small Business RV Series Routers offer virtual private networking (VPN) technology so your remote workers can connect to your network through a secure Internet pathway." Source: https://www.cisco.com/c/en/us/products/routers/small-business-rv-series-routers/index.html Business recommendation: ------------------------ We want to thank Cisco for the very quick and professional response and great coordination. Customers are urged to update the firmware of their devices. Vulnerability overview/description: ----------------------------------- 1) Hardcoded Credentials The device contains hardcoded users and passwords which can be used to login via SSH on an emulated device at least. During the communication with Cisco it turned out that: "Accounts like the 'debug-admin' and 'root' can not be accessed from console port, CLI or webui". Therefore, these accounts had no real functionality and cannot be used for malicious actions. 2) Known GNU glibc Vulnerabilities The used GNU glibc in version 2.19 is outdated and contains multiple known vulnerabilities. The outdated version was found by IoT Inspector. 3) Known BusyBox Vulnerabilities The used BusyBox toolkit in version 1.23.2 is outdated and contains multiple known vulnerabilities. The outdated version was found by IoT Inspector. One of the discovered vulnerabilities (CVE-2017-16544) was verified by using the MEDUSA scaleable firmware runtime. 4) Multiple Vulnerabilities - IoT Inspector Report Further information can be found in IoT Inspector report: https://r.sec-consult.com/ciscoiot Proof of concept: ----------------- 1) Hardcoded Credentials The following hardcoded hashes were found in the 'shadow' file of the firmware: root:$1$hPNSjUZA$7eKqEpqVYltt9xJ6f0OGf0:15533:0:99999:7::: debug-admin:$1$.AAm0iJ4$na9wZwly9pSrdS8MhcGKw/:15541:0:99999:7::: [...] The undocumented user 'debug-admin' is also contained in this file.

Weber / @2019 . The first vulnerability listed below is considered to have critical impact. CVE-2015-7547 The Google Security Team and Red Hat discovered that the glibc host name resolver function, getaddrinfo, when processing AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its internal buffers, leading to a stack-based buffer overflow and arbitrary code execution. This vulnerability affects most applications which perform host name resolution using getaddrinfo, including system services. CVE-2015-8776 Adam Nielsen discovered that if an invalid separated time value is passed to strftime, the strftime function could crash or leak information. Applications normally pass only valid time information to strftime; no affected applications are known. CVE-2015-8778 Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r functions did not check the size argument properly, leading to a crash (denial of service) for certain arguments. No impacted applications are known at this time. CVE-2015-8779 The catopen function contains several unbound stack allocations (stack overflows), causing it the crash the process (denial of service). No applications where this issue has a security impact are currently known. While it is only necessary to ensure that all processes are not using the old glibc anymore, it is recommended to reboot the machines after applying the security upgrade. For the stable distribution (jessie), these problems have been fixed in version 2.19-18+deb8u3. For the unstable distribution (sid), these problems will be fixed in version 2.21-8
