Debian: DSA-2123-1 Critical: Glibc Input Sanitization Flaw

Ben Hawkes and Tavis Ormandy discovered that the dynamic loader in GNU
libc allows local users to gain root privileges using a crafted
LD_AUDIT environment variable.

For the stable distribution (lenny), this problem has been fixed in
version 2.7-18lenny6.

For the upcoming stable distribution (squeeze), this problem has been
fixed in version 2.11.2-6+squeeze1 of the eglibc package.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your glibc packages.
