Bug 115324 – net-www/apache Possible DoS (CVE-2005-3357)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Sune Kloppenborg Jeppesen (RETIRED) 2005-12-12 10:15:53 UTC]

It's a remotely-triggered NULL pointer dereference (so interesting only if you 
use a threaded MPM), affects server configurations with an SSL vhost 
configured with access control and a custom 400 errordocument

Apache herd, please advise/patch ?

[Comment 2 Stuart Herbert (RETIRED) 2005-12-20 05:19:42 UTC]

Looks like we need this patch to fix the problem:

http://svn.apache.org/viewcvs.cgi/httpd/httpd/trunk/modules/ssl/ssl_engine_kernel.c?rev=354394&view=diff&r1=354394&r2=354393&p1=httpd/httpd/trunk/modules/ssl/ssl_engine_kernel.c&p2=/httpd/httpd/trunk/modules/ssl/ssl_engine_kernel.c

Best regards,
Stu

The supplied patch is for the apache trunk and won't apply correctly to 2.0.55. We need a backport from upstream unless someone more knowledgable in c/c++ wants to step up to the plate.

[Comment 4 Thierry Carrez (RETIRED) 2005-12-21 01:28:48 UTC]

Given the very specific nature of this vulnerability I would wait for an upstream release to pick it up.

[Comment 5 Thierry Carrez (RETIRED) 2006-01-13 06:06:21 UTC]

Backports at :
http://issues.apache.org/bugzilla/show_bug.cgi?id=37791#c3

This should be grouped with bug 118875 for a common GLSA.

[Comment 6 Michael Stewart (vericgar) (RETIRED) 2006-01-16 19:03:36 UTC]

fixed in CVS. see bug 118875.

See stable marking handled on bug 118875

[Comment 8 Thierry Carrez (RETIRED) 2006-01-23 00:56:09 UTC]

Common GLSA with bug 118875

[Comment 9 Sune Kloppenborg Jeppesen (RETIRED) 2006-02-06 10:24:00 UTC]

GLSA 200602-03

Apache note that new old style versions might be flagged as vulnerable by this GLSA. So we have to update it if you put out new versions.
