-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2015.0900 SOL16364: GNU C Library (glibc) vulnerability CVE-2012-3406 8 April 2015 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: F5 BIG-IP products F5 Enterprise Manager Publisher: F5 Networks Operating System: Network Appliance Impact/Access: Execute Arbitrary Code/Commands -- Existing Account Denial of Service -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2012-3406 Reference: ESB-2015.0428 ESB-2012.0811 ESB-2012.0797 ESB-2012.0687 ESB-2013.0010.3 Original Bulletin: https://support.f5.com/kb/en-us/solutions/public/16000/300/sol16364.html - --------------------------BEGIN INCLUDED TEXT-------------------- SOL16364: GNU C Library (glibc) vulnerability CVE-2012-3406 Security Advisory Original Publication Date: 04/03/2015 Description The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405. (CVE-2012-3406) Impact An attacker with local access and knowledge of how to make the glibc function trigger an exploit may be able to cause a denial-of-service (DoS) or run arbitrary code. Status F5 Product Development has assigned ID 391780 (BIG-IP) to this vulnerability, and has evaluated the currently supported releases for potential vulnerability. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases or hotfixes that address the vulnerability, refer to the following table: Product Versions known to be vulnerable Versions known to be not vulnerable Severity Vulnerable component or feature BIG-IP LTM 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc 10.1.0 - 10.2.4 BIG-IP AAM None 11.4.0 - 11.6.0 Not vulnerable None BIG-IP AFM None 11.3.0 - 11.6.0 Not vulnerable None BIG-IP Analytics 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc BIG-IP APM 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc 10.1.0 - 10.2.4 BIG-IP ASM 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc 10.1.0 - 10.2.4 BIG-IP Edge Gateway 11.0.0 - 11.2.1 11.3.0 low glibc 10.1.0 - 10.2.4 BIG-IP GTM 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc 10.1.0 - 10.2.4 BIG-IP Link Controller 11.0.0 - 11.2.1 11.3.0 - 11.6.0 low glibc 10.1.0 - 10.2.4 BIG-IP PEM None 11.3.0 - 11.6.0 Not vulnerable None BIG-IP PSM 11.0.0 - 11.2.1 11.3.0 - 11.4.1 low glibc 10.1.0 - 10.2.4 BIG-IP WebAccelerator 11.0.0 - 11.2.1 11.3.0 low glibc 10.1.0 - 10.2.4 BIG-IP WOM 11.0.0 - 11.2.1 11.3.0 low glibc 10.1.0 - 10.2.4 ARX None 6.0.0 - 6.4.0 Not vulnerable None Enterprise Manager 3.0.0 3.1.0 - 3.1.1 low glibc 2.1.0 - 2.3.0 FirePass None 7.0.0 Not vulnerable None 6.0.0 - 6.1.0 BIG-IQ Cloud None 4.0.0 - 4.5.0 Not vulnerable None BIG-IQ Device None 4.2.0 - 4.5.0 Not vulnerable None BIG-IQ Security None 4.0.0 - 4.5.0 Not vulnerable None BIG-IQ ADC None 4.5.0 Not vulnerable None LineRate None 2.5.0 Not vulnerable None 2.4.0 - 2.4.2 F5 WebSafe None 1.0.0 Not vulnerable None Traffix SDC None 3.3.2 - 3.5.1 Not vulnerable None 4.0.0 - 4.1.0 BIG-IP Edge Clients None 2.0.0 - 2.0.6 Not vulnerable None for Android BIG-IP Edge Clients None 2.0.0 - 2.0.4 Not vulnerable None for Apple iOS 1.0.5 - 1.0.6 BIG-IP Edge Clients None 6035.x - 7110.x Not vulnerable None for Linux BIG-IP Edge Clients None 6035.x - 7110.x Not vulnerable None for MAC OS X BIG-IP Edge Clients None 6035.x - 7110.x Not vulnerable None for Windows BIG-IP Edge Clients None 1.0.0.x Not vulnerable None Windows Phone 8.1 BIG-IP Edge Portal None 1.0.0 - 1.0.2 Not vulnerable None for Android BIG-IP Edge Portal None 1.0.0 - 1.0.3 Not vulnerable None for Apple iOS Note: As of February 17, 2015, AskF5 Security Advisory articles include the Severity value. Security Advisory articles published before this date do not list a Severity value. Recommended Action If the previous table lists a version in the Versions known to be not vulnerable column, you can eliminate this vulnerability by upgrading to the listed version. If the listed version is older than the version you are currently running, or if the table does not list any version in the column, then no upgrade candidate currently exists. F5 responds to vulnerabilities in accordance with the Severity values published in the previous table. The Severity values and other security vulnerability parameters are defined in SOL4602: Overview of the F5 security vulnerability response policy. To mitigate this vulnerability, you should permit access to F5 products only over a secure network, and limit login access to trusted users. For additional information, refer to SOL13092: Overview of securing access to the BIG-IP system.
