New! Plugin Severity Now Using CVSS v3

Synopsis
The remote Debian host is missing a security-related update.Description
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.Solution
Upgrade the apr packages and restart the apache2 server.For the oldstable distribution (lenny), this problem has been fixed in version 1.2.12-5+lenny3.
For the stable distribution (squeeze), this problem has been fixed in version 1.4.2-6+squeeze1.
