Package        : apr-util
Vulnerability  : denial of service
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2010-1623

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.

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.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1.3.9+dfsg-4.

We recommend that you upgrade your apr-util packages.
