Background ========== Pound is a reverse proxy, load balancer and HTTPS front-end. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/pound < 1.8.3 >= 1.8.3 Description =========== Steven Van Acker has discovered a buffer overflow vulnerability in the "add_port()" function in Pound. Impact ====== A remote attacker could send a request for an overly long hostname parameter, which could lead to the remote execution of arbitrary code with the rights of the Pound daemon process (by default, Gentoo uses the "nobody" user to run the Pound daemon). Workaround ========== There is no known workaround at this time. Resolution ========== All Pound users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/pound-1.8.3" References ========== [ 1 ] Original announcement http://www.apsis.ch/pound/pound_list/archive/2005/2005-04/1114516112000 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-29.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.

ping
Pound is on 9.2 and 9.3. I'd suggest to update to 1.9 for both. I don't expect any compatibility issues with that.
Did you actually look at the code? It's a one line fix, no version update for that one.
Created attachment 38585 [details] pound-1.8.2-CAN-2005-1391.diff stripped diff 1.8.2->1.8.3. Only the last hunk is the security fix (CAN-2005-1391). The first two are bugfixes and probably make sense. The -1 is not needed in snprintf but upsteam fixed it that way.

I've submitted the version update for STABLE. Verified with author that the one-line patch is all we need to fix the issue. I'll submit patched packages for SL 9.2/9.3. aj doesn't want the version upgrade for those.
Submitted packages for SL 9.2/9.3. I did mbuild both on the corresponding distro, but it wouldn't hurt if someone double-checked if the packages are ok, as this is my first security fix. ;-)
The sad truth is that noone is going to test it.
