Synopsis: Important: glibc security update
Issue date: 2011-04-04
CVE Names: CVE-2011-0536
CVE-2011-1071
CVE-2011-1095
The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system
cannot function properly.
The fix for CVE-2010-3847 introduced a regression in the way the dynamic
loader expanded the $ORIGIN dynamic string token specified in the RPATH
and RUNPATH entries in the ELF library header. A local attacker could
use this flaw to escalate their privileges via a setuid or setgid
program using such a library. (CVE-2011-0536)
It was discovered that the glibc fnmatch() function did not properly
restrict the use of alloca(). If the function was called on sufficiently
large inputs, it could cause an application using fnmatch() to crash or,
possibly, execute arbitrary code with the privileges of the application.
(CVE-2011-1071)
It was discovered that the locale command did not produce properly
escaped output as required by the POSIX specification. If an attacker
were able to set the locale environment variables in the environment of
a script that performed shell evaluation on the output of the locale
command, and that script were run with different privileges than the
attacker's, it could execute arbitrary code with the privileges of the
script. (CVE-2011-1095)
All users should upgrade to these updated packages, which contain
backported patches to correct these issues.
