Bug#627182: libapr1: last security update introduces a infinite loop condition

Package: libapr1
Version: 1.4.2-8
Severity: important
Tags: upstream


We have found that the last security update (1.4.2-6+squeeze1, 1.2.12-5+lenny3)
causes apr_fnmatch to enter an infinite loop, on particular patters.

For instance, with the following configuration directive:
    <Location "/*/WEB-INF/">
        deny from all
if someone visits any URL, an apache2 thread will start consuming 100% CPU.

This is introduced by the backport
debian/patches/028_fnmatch_CVE-2011-0419.dpatch, but it can be reproduced with the vanilla apr.
