Detail

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).

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

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you update your ident2 package.

Id Description
5605 ident2 child_service Overflow

A remote overflow exists in ident2. Ident2 fails to check a buffer length in the child_service function resulting in a buffer overflow. With a specially crafted request, an attacker can cause buffer overflow and execute arbitrary codes, resulting in a loss of integrity.
