Debian DSA-149-1 : glibc - integer overflow

critical Nessus Plugin ID 14986

Synopsis

The remote Debian host is missing a security-related update.

Description

An integer overflow bug has been discovered in the RPC library used by GNU libc, which is derived from the SunRPC library. This bug could be exploited to gain unauthorized root access to software linking to this code. The packages below also fix integer overflows in the malloc code. They also contain a fix from Andreas Schwab to reduce linebuflen in parallel to bumping up the buffer pointer in the NSS DNS code.

Solution

Upgrade the libc6 packages immediately.

This problem has been fixed in version 2.1.3-23 for the old stable distribution (potato), in version 2.2.5-11.1 for the current stable distribution (woody) and in version 2.2.5-13 for the unstable distribution (sid).
