Description

Sebastian Krahmer discovered several remotely exploitable buffer overflow vulnerabilities in the MSN component of gaim.

In two places in the MSN protocol plugins (object.c and slp.c), strncpy was used incorrectly; the size of the array was not checked before copying to it. Both bugs affect MSN's MSNSLP protocol, which is peer-to-peer, so this could potentially be easy to exploit.
