Debian DSA-2117-1 : apr-util - denial of service

medium Nessus Plugin ID 49767

Language:

Synopsis

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

Description

APR-util is part of the Apache Portable Runtime library which is used by projects such as Apache httpd and Subversion.

Jeff Trawick discovered a flaw in the apr_brigade_split_line() function in apr-util. A remote attacker could send crafted http requests to cause a greatly increased memory consumption in Apache httpd, resulting in a denial of service.

Solution

Upgrade the apr-util packages.

This upgrade fixes this issue. After the upgrade, any running apache2 server processes need to be restarted.

For the stable distribution (lenny), this problem has been fixed in version 1.2.12+dfsg-8+lenny5.
