CVE-2015-0235

TITLE

GNU C Library (glibc) __nss_hostname_digits_dots() function vulnerable to buffer overflow

DESCRIPTION

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST.". This vulnerability has been assigned CVE-2015-0235, and is referred to in the media by the name "GHOST". This vulnerability has been assigned CVE-2015-0235, and is referred to in the media by the name "GHOST". Relevant releases/architectures: RHEV Hypervisor for RHEL-6 - noarch 3. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. (CVE-2015-0235) A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. (CVE-2014-3611) A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions. (CVE-2014-3511) A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. (CVE-2014-3567) It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept (Invalidate Translations Derived from EPT) and invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invept/invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. Bugs fixed (https://bugzilla.redhat.com/): 1127504 - CVE-2014-3511 openssl: TLS protocol downgrade attack 1144825 - CVE-2014-3646 kernel: kvm: vmx: invvpid vm exit not handled 1144835 - CVE-2014-3645 kernel: kvm: vmx: invept vm exit not handled 1144878 - CVE-2014-3611 kernel: kvm: PIT timer race condition 1152563 - Tracker: RHEV-H 6.6 for RHEV 3.4.z build 1152961 - CVE-2014-3567 openssl: Invalid TLS/SSL session tickets could cause memory leak leading to server crash 1180044 - Incorrect glusterfs package in to RHEVH 6.6 for 3.4.4 and 3.5 build [rhev-3.4.z] 1183461 - CVE-2015-0235 glibc: __nss_hostname_digits_dots() heap-based buffer overflow 1185720 - Incorrect rhn-virtualization-host and rhn-virtualization-common packages in RHEVH 6.6 for rhev 3.4.5 6. The original glibc bug was reported by Peter Klotz. CVE-2014-7817 Tim Waugh of Red Hat discovered that the WRDE_NOCMD option of the wordexp function did not suppress command execution in all cases. This allows a context-dependent attacker to execute shell commands. CVE-2012-6656 CVE-2014-6040 The charset conversion code for certain IBM multi-byte code pages could perform an out-of-bounds array access, causing the process to crash. In some scenarios, this allows a remote attacker to cause a persistent denial of service. For the upcoming stable distribution (jessie) and the unstable distribution (sid), the CVE-2015-0235 issue has been fixed in version 2.18-1 of the glibc package. We recommend that you upgrade your eglibc packages. 6.5) - i386, ppc64, s390x, x86_64 3. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-0235 https://rhn.redhat.com/errata/RHSA-2015-0092.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 678efef85b85206451ef8927bad808e0 mbs1/x86_64/glibc-2.14.1-12.11.mbs1.x86_64.rpm 46cd508f03e36c1e4f752c317852ec8e mbs1/x86_64/glibc-devel-2.14.1-12.11.mbs1.x86_64.rpm 069302c80e3b79504e2b0eaaa72c2745 mbs1/x86_64/glibc-doc-2.14.1-12.11.mbs1.noarch.rpm 3a841c0295823354655dd3e7734ada0b mbs1/x86_64/glibc-doc-pdf-2.14.1-12.11.mbs1.noarch.rpm 11a672a0b4bae77c7adfa803bea9871f mbs1/x86_64/glibc-i18ndata-2.14.1-12.11.mbs1.x86_64.rpm d3f113ccec4f18e4bb08c951625e51d7 mbs1/x86_64/glibc-profile-2.14.1-12.11.mbs1.x86_64.rpm f6d6aa5806dd747e66996ea8cc01c9b4 mbs1/x86_64/glibc-static-devel-2.14.1-12.11.mbs1.x86_64.rpm 98cc6eae0234eeed945712bbc8b2c0ea mbs1/x86_64/glibc-utils-2.14.1-12.11.mbs1.x86_64.rpm bf6f2fcc3dd21bd8380aac40e91bb802 mbs1/x86_64/nscd-2.14.1-12.11.mbs1.x86_64.rpm f597e4d6241c76701733d730e84f5714 mbs1/SRPMS/glibc-2.14.1-12.11.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.

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 remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235) Red Hat would like to thank Qualys for reporting this issue. 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. This update is available via the Red Hat Network.

SEC Consult Vulnerability Lab Security Advisory < 20210901-0 > ======================================================================= title: Multiple vulnerabilities product: see "Vulnerable / tested versions" vulnerable version: see "Vulnerable / tested versions" fixed version: see "Solution" CVE number: CVE-2021-39278, CVE-2021-39279 impact: High homepage: https://www.moxa.com/ found: 2020-08-31 by: T. Weber (Office Vienna) SEC Consult Vulnerability Lab An integrated part of SEC Consult, an Atos company Europe | Asia | North America https://www.sec-consult.com ======================================================================= Vendor description: ------------------- "Together, We Create Change Moxa is committed to making a positive impact around the world.

Source: https://www.moxa.com/en/about-us/corporate-responsibility Business recommendation: ------------------------ SEC Consult recommends to immediately apply the available patches from the vendor. A thorough security review should be performed by security professionals to identify further potential security issues. Vulnerability overview/description: ----------------------------------- 1) Authenticated Command Injection (CVE-2021-39279) An authenticated command injection vulnerability can be triggered by issuing a GET request to the "/forms/web_importTFTP" CGI program which is available on the web interface. An attacker can abuse this vulnerability to compromise the operating system of the device. This issue was found by emulating the firmware of the device. 2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278) Via a crafted config-file, a reflected cross-site scripting vulnerability can be exploited in the context of the victim's browser. This config-file can be uploaded to the device via the "Config Import Export" tab in the main menu. 3) Known GNU glibc Vulnerabilities (CVE-2015-0235) The used GNU glibc in version 2.9 is outdated and contains multiple known vulnerabilities. One of the discovered vulnerabilities (CVE-2015-0235, gethostbyname "GHOST" buffer overflow) was verified by using the MEDUSA scalable firmware runtime. 4) Multiple Outdated Software Components Multiple outdated software components containing vulnerabilities were found by the IoT Inspector. The vulnerabilities 1), 2) and 3) were manually verified on an emulated device by using the MEDUSA scalable firmware runtime. Proof of concept: ----------------- 1) Authenticated Command Injection (CVE-2021-39279) The vulnerability can be triggered by navigating in the web interface to the tab: "Main Menu"->"Maintenance"->"Config Import Export" The "TFTP Import" menu is prone to command injection via all parameters. To exploit the vulnerability, an IP address, a configuration path and a filename must be set. If the filename is used to trigger the exploit, the payload in the interceptor proxy would be: http://192.168.1.1/forms/web_importTFTP?servIP=192.168.1.1&configPath=/&fileName=name|`ping localhost -c 100` 2) Reflected Cross-Site Scripting via Manipulated Config-File (CVE-2021-39278) The vulnerability can be triggered by navigating in the web interface to the tab: "Main Menu"->"Maintenance"->"Config Import Export" The "Config Import" menu is prone to reflected cross-site scripting via the upload of config files. Example of malicious config file: ------------------------------------------------------------------------------- [board] deviceName="WAC-2004_0000</span><script>alert(document.cookie)</script>" deviceLocation="" [..] ------------------------------------------------------------------------------- Uploading such a crafted file triggers cross-site scripting as the erroneous value is displayed without filtering characters. 3) Known GNU glibc Vulnerabilities (CVE-2015-0235) GNU glibc version 2.9 contains multiple CVEs like: CVE-2016-1234, CVE-2015-7547, CVE-2013-7423, CVE-2013-1914, and more. The gethostbyname buffer overflow vulnerability (GHOST) was checked with the help of the exploit code from https://seclists.org/oss-sec/2015/q1/274. It was compiled and executed on the emulated device to test the system. 4) Multiple Outdated Software Components The IoT Inspector recognized multiple outdated software components with known vulnerabilities: BusyBox 1.18.5 06/2011 Dropbear SSH 2011.54 11/2011 GNU glibc 2.9 02/2009 Linux Kernel 2.6.27 10/2008 OpenSSL 0.9.7g 04/2005 Only found in the program "iw_director" OpenSSL 1.0.0 03/2010 Vulnerable / tested versions: ----------------------------- The following firmware versions for various devices have been identified to be vulnerable: * WAC-2004 / 1.7 * WAC-1001 / 2.1 * WAC-1001-T / 2.1 * OnCell G3470A-LTE-EU / 1.7 * OnCell G3470A-LTE-EU-T / 1.7 * TAP-323-EU-CT-T / 1.3 * TAP-323-US-CT-T / 1.3 * TAP-323-JP-CT-T / 1.3 * WDR-3124A-EU / 2.3 * WDR-3124A-EU-T / 2.3 * WDR-3124A-US / 2.3 * WDR-3124A-US-T / 2.3 Vendor contact timeline: ------------------------ 2020-10-09: Contacting vendor through moxa.csrt@moxa.com. 2020-10-12: Contact sends PGP key for encrypted communication and asks for the detailed advisory.
