The glibc packages provide the standard C and standard math libraries used
by multiple programs on the system. Without these libraries, the Linux
system cannot function properly.

Multiple integer overflow flaws, leading to stack-based buffer overflows,
were found in glibc’s functions for converting a string to a numeric
representation (strtod(), strtof(), and strtold()). If an application used
such a function on attacker controlled input, it could cause the
application to crash or, potentially, execute arbitrary code.
(CVE-2012-3480)

All users of glibc are advised to upgrade to these updated packages, which
contain a backported patch to correct these issues.
