An eglibc security update has been released for Debian 6 LTS

Package : eglibc
Version : eglibc_2.11.3-4+deb6u9
CVE ID : CVE-2014-9761 CVE-2015-8776 CVE-2015-8778 CVE-2015-8779

Several vulnerabilities have been fixed in the Debian GNU C Library,
eglibc:

CVE-2014-9761

The math's nan* function wrongly handled payload strings, yielding
to an unbounded stack allocation based on the length of the
arguments. To solve this issue, payload parsing has been refactored
out of strtod into a separate functions that nan* can call directly.

CVE-2015-8776

The strftime() function made it possible to access invalid memory,
allowing to segfault the calling application.

CVE-2015-8778

hcreate() was susceptible to an integer overflow, that may results
in out-of-bounds heap accesses.

CVE-2015-8779

The catopen() function suffered from multiple unbounded stack
allocations.

For Debian 6 "Squeeze", these issues have been fixed in eglibc version
eglibc_2.11.3-4+deb6u9. We recommend you to upgrade your eglibc
packages.
