Ubuntu Security Notice USN-177-1 September 07, 2005
apache2, libapache-mod-ssl vulnerabilities
CAN-2005-2700, CAN-2005-2728
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
The following packages are affected:
apache2-mpm-perchild
apache2-mpm-prefork
apache2-mpm-threadpool
apache2-mpm-worker
libapache-mod-ssl
The problem can be corrected by upgrading the affected package to
version 2.0.50-12ubuntu4.8 (for Ubuntu 4.10), or 2.0.53-5ubuntu5.3
(for Ubuntu 5.04). In general, a standard system upgrade is sufficient
to effect the necessary changes.
Details follow:
Apache did not honour the "SSLVerifyClient require" directive within a
<Location> block if the surrounding <VirtualHost> block contained a
directive "SSLVerifyClient optional". This allowed clients to bypass
client certificate validation on servers with the above configuration.
(CAN-2005-2700)
Filip Sneppe discovered a Denial of Service vulnerability in the byte
range filter handler. By requesting certain large byte ranges, a
remote attacker could cause memory exhaustion in the server.
(CAN-2005-2728)
The updated libapache-mod-ssl also fixes two older Denial of Service
vulnerabilities: A format string error in the ssl_log() function which
could be exploited to crash the server (CAN-2004-0700), and a flaw in
the SSL cipher negotiation which could be exploited to terminate a
session (CAN-2004-0885). Please note that Apache 1.3 and
libapache-mod-ssl are not officially supported (they are in the
"universe" component of the Ubuntu archive).
Updated packages for Ubuntu 4.10 (Warty Warthog):
