Detail

The recent APR update DSA-2237-1 introduced a regression that could lead to an endless loop in the apr_fnmatch() function, causing a denial of service. This update fixes this problem (CVE-2011-1928).

For reference, the description of the original DSA, which fixed CVE-2011-0419:

A flaw was found in the APR library, which could be exploited through Apache HTTPD's mod_autoindex. If a directory indexed by mod_autoindex contained files with sufficiently long names, a remote attacker could send a carefully crafted request which would cause excessive CPU usage. This could be used in a denial of service attack.

For the oldstable distribution (lenny), this problem has been fixed in version 1.2.12-5+lenny4.

For the stable distribution (squeeze), this problem has been fixed in version 1.4.2-6+squeeze2.

For the testing distribution (wheezy), this problem will be fixed in version 1.4.5-1.

For the unstable distribution (sid), this problem will be fixed in version 1.4.5-1.

We recommend that you upgrade your apr packages and restart the apache2 server.
