apr -- multiple vunerabilities

Secunia reports:

Multiple vulnerabilities have been reported in APR-util, which can be exploited by malicious people to cause a DoS (Denial of Service).

Two XML parsing vulnerabilities exist in the bundled version of expat.

An error within the "apr_brigade_split_line()" function in buckets/apr_brigade.c can be exploited to cause high memory consumption.
