Debian DSA-805-1 : apache2 - several vulnerabilities

critical Nessus Plugin ID 19612

Synopsis

The remote Debian host is missing a security-related update.

Description

Several problems have been discovered in Apache2, the next generation, scalable, extendable web server. The Common Vulnerabilities and Exposures project identifies the following problems :

- CAN-2005-1268 Marc Stern discovered an off-by-one error in the mod_ssl Certificate Revocation List (CRL) verification callback.
When Apache is configured to use a CRL this can be used to cause a denial of service.

- CAN-2005-2088

A vulnerability has been discovered in the Apache web server. When it is acting as an HTTP proxy, it allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct cross-site scripting attacks, which causes Apache to incorrectly handle and forward the body of the request.

- CAN-2005-2700

A problem has been discovered in mod_ssl, which provides strong cryptography (HTTPS support) for Apache that allows remote attackers to bypass access restrictions.

- CAN-2005-2728

The byte-range filter in Apache 2.0 allows remote attackers to cause a denial of service via an HTTP header with a large Range field.

Solution

Upgrade the apache2 packages.

The old stable distribution (woody) does not contain Apache2 packages.

For the stable distribution (sarge) these problems have been fixed in version 2.0.54-5.
