Detailsinfo

A vulnerability was found in Canonical Ubuntu Linux 12.04 (Operating System) and classified as critical. Affected by this issue is the function vfprintf. The manipulation with an unknown input leads to a numeric error vulnerability. Using CWE to declare the problem leads to CWE-189. Impacted is availability. CVE summarizes:

The vfprintf function in stdio-common/vfprintf.c in libc in GNU C Library (aka glibc) 2.14 and other versions does not properly calculate a buffer length, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (segmentation fault and crash) via a format string with a large number of format specifiers that triggers "desynchronization within the buffer size handling," a different vulnerability than CVE-2012-3404.

The weakness was presented 02/10/2014 by Stefan Cornelius as Bug 13446 as confirmed bug report (Bugzilla). The advisory is available at sourceware.org. This vulnerability is handled as CVE-2012-3405 since 06/14/2012. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 82149 (Debian DLA-165-1 : eglibc security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 216049 (VMWare ESXi 5.1.0 Patch Complete Update 1 Missing (KB2041632)).
