"The strxfrm() function is vulnerable to integer overflows when
computing memory allocation sizes (similar to CVE-2012-4412).
Furthermore since it fallbacks to use alloca() when malloc() fails, it
is vulnerable to stack-based buffer overflows (similar to
CVE-2012-4424).

Those issues have been fixed in Debian 6 Squeeze with eglibc
2.11.3-4+deb6u8. We recommend that you upgrade libc6 and other
packages provided by eglibc.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
