RedHat Security Advisory RHSA-2009:1204

Summary
The remote host is missing updates announced in advisory RHSA-2009:1204. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way the Apache Portable Runtime (APR) manages memory pool and relocatable memory allocations. An attacker could use these flaws to issue a specially-crafted request for memory allocation, which would lead to a denial of service (application crash) or, potentially, execute arbitrary code with the privileges of an application using the APR libraries. (CVE-2009-2412) All apr and apr-util users should upgrade to these updated packages, which contain backported patches to correct these issues. Applications using the APR libraries, such as httpd, must be restarted for this update to take effect.
