Debian DSA-494-1 : ident2 - buffer overflow

high Nessus Plugin ID 15331

Synopsis

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

Description

Jack <> discovered a buffer overflow in ident2, an implementation of the ident protocol (RFC1413), where a buffer in the child_service function was slightly too small to hold all of the data which could be written into it. This vulnerability could be exploited by a remote attacker to execute arbitrary code with the privileges of the ident2 daemon (by default, the 'identd' user).

Solution

For the current stable distribution (woody) this problem has been fixed in version 1.03-3woody1.

We recommend that you update your ident2 package.
