Medium Nessus Plugin ID 68155
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2010:0950 :
Updated apr-util 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. apr-util is a library which provides additional utility interfaces for APR; including support for XML parsing, LDAP, database interfaces, URI parsing, and more.
It was found that certain input could cause the apr-util library to allocate more memory than intended in the apr_brigade_split_line() function. An attacker able to provide input in small chunks to an application using the apr-util library (such as httpd) could possibly use this flaw to trigger high memory consumption. (CVE-2010-1623)
All apr-util users should upgrade to these updated packages, which contain a backported patch to correct this issue. Applications using the apr-util library, such as httpd, must be restarted for this update to take effect.
SolutionUpdate the affected apr-util packages.
