Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200608-01 (Apache: Off-by-one flaw in mod_rewrite)

An off-by-one flaw has been found in Apache's mod_rewrite module by Mark Dowd of McAfee Avert Labs. This flaw is exploitable depending on the types of rewrite rules being used. Impact :

A remote attacker could exploit the flaw to cause a Denial of Service or execution of arbitrary code. Note that Gentoo Linux is not vulnerable in the default configuration. Workaround :

There is no known workaround at this time.

Solution

All Apache users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose www-servers/apache
