"Multiple vulnerabilities was discovered and fixed in glibc :

Multiple untrusted search path vulnerabilities in elf/dl-object.c in
certain modified versions of the GNU C Library (aka glibc or libc6),
including glibc-2.5-49.el5_5.6 and glibc-2.12-1.7.el6_0.3 in Red Hat
Enterprise Linux, allow local users to gain privileges via a crafted
dynamic shared object (DSO) in a subdirectory of the current working
directory during execution of a (1) setuid or (2) setgid program that
has in (a) RPATH or (b) RUNPATH. NOTE: this issue exists because of an
incorrect fix for CVE-2010-3847 (CVE-2011-0536).

The GNU C Library (aka glibc or libc6) before 2.12.2 and Embedded
GLIBC (EGLIBC) allow context-dependent attackers to execute arbitrary
code or cause a denial of service (memory consumption) via a long UTF8
string that is used in an fnmatch call, aka a stack extension attack,
a related issue to CVE-2010-2898, as originally reported for use of
this library by Google Chrome (CVE-2011-1071).

The addmntent function in the GNU C Library (aka glibc or libc6) 2.13
and earlier does not report an error status for failed attempts to
write to the /etc/mtab file, which makes it easier for local users to
trigger corruption of this file, as demonstrated by writes from a
process with a small RLIMIT_FSIZE value, a different vulnerability
than CVE-2010-0296 (CVE-2011-1089).

locale/programs/locale.c in locale in the GNU C Library (aka glibc or
libc6) before 2.13 does not quote its output, which might allow local
users to gain privileges via a crafted localization environment
variable, in conjunction with a program that executes a script that
uses the eval function (CVE-2011-1095).

Integer overflow in posix/fnmatch.c in the GNU C Library (aka glibc or
libc6) 2.13 and earlier allows context-dependent attackers to cause a
denial of service (application crash) via a long UTF8 string that is
used in an fnmatch call with a crafted pattern argument, a different
vulnerability than CVE-2011-1071 (CVE-2011-1659).

crypt_blowfish before 1.1, as used in glibc on certain platforms, does
not properly handle 8-bit characters, which makes it easier for
context-dependent attackers to determine a cleartext password by
leveraging knowledge of a password hash (CVE-2011-2483).

The updated packages have been patched to correct these issues."
