Vulnerability Assessment Details

USN177-1 : apache2, libapache-mod-ssl vulnerabilities

Vulnerability Assessment Summary
apache2, libapache-mod-ssl vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- apache2
- apache2-common
- apache2-doc
- apache2-mpm-perchild
- apache2-mpm-prefork
- apache2-mpm-threadpool
- apache2-mpm-worker
- apache2-prefork-dev
- apache2-threaded-dev
- apache2-utils
- libapache-mod-ssl
- libapache-mod-ssl-doc
- libapr0
- libapr0-dev


Description :

Apache did not honour the "SSLVerifyClient require" directive within a
block if the surrounding block contained a
directive "SSLVerifyClient optional". This permited clients to bypass
client certificate validation on servers with the above configuration.
(CVE-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.
(CVE-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 (CVE-2004-0700), and a flaw in
the SSL cipher negotiation which could be exploited to terminate a
session (CVE-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).

Solution :
