Summary

The Apache Portable Runtime (APR) is a portability library used by the Apache HTTP Server and other projects. It aims to provide a free library of C data structures and routines. apr-util is a utility library used with APR. This library provides additional utility interfaces for APR; including support for XML parsing, LDAP, database interfaces, URI parsing, and more.
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.
