Description Robert Buchholz (RETIRED) gentoo-dev 2008-03-05 09:58:32 UTC

A vulnerability has been reported in SILC (Secure Internet Live Conferencing) Toolkit, which potentially can be exploited by malicious people to compromise an application using the toolkit.

The vulnerability is caused due to a boundary error within the function "silc_fingerprint()" in lib/silcutil/silcutil.c, which can be exploited to cause a stack-based buffer overflow if overly long data is passed to the function.

The vulnerability is reported in versions prior to 1.1.6.

I'm not sure how an attacker can generate input to that function, maybe you guys from net-irc can help here.

Also, is 1.1.6 good to go stable?
