Debian Security Advisory DSA 769-1 – Szymon Zygmunt and Michal Bartoszkiewicz discovered a memory alignment error in libgadu (from ekg, console Gadu Gadu client, an instant messaging program) which is included in gaim, a multi-protocol instant messaging client, as well. This can not be exploited on the x86 architecture but on others, e.g. on Sparc and lead to a bus error, in other words a denial of service.
