New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated apr packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The Apache Portable Runtime (APR) is a portability library used by the Apache HTTP Server and other projects. It provides a free library of C data structures and routines.

It was discovered that the apr_fnmatch() function used an unconstrained recursion when processing patterns with the '*' wildcard. An attacker could use this flaw to cause an application using this function, which also accepted untrusted input as a pattern for matching (such as an httpd server using the mod_autoindex module), to exhaust all stack memory or use an excessive amount of CPU time when performing matching. (CVE-2011-0419)

Red Hat would like to thank Maksymilian Arciemowicz for reporting this issue.

All apr users should upgrade to these updated packages, which contain a backported patch to correct this issue. Applications using the apr library, such as httpd, must be restarted for this update to take effect.

Solution

Update the affected packages.
