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.
