Synopsis: Moderate: httpd security and bug fix update
Issue date: 2009-08-10
CVE Names: CVE-2009-1891 CVE-2009-2412
CVE-2009-1891 httpd: possible temporary DoS (CPU consumption) in mod_deflate
CVE-2009-2412 apr, apr-util: Integer overflows in memory pool (apr) and
relocatable memory (apr-util) management
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)
A denial of service flaw was found in the Apache mod_deflate module.
This module continued to compress large files until compression was
complete, even if the network connection that requested the content was
closed before compression completed. This would cause mod_deflate to
consume large amounts of CPU if mod_deflate was enabled for a large
file. (CVE-2009-1891)
This update also fixes the following bug:
* in some cases the Content-Length header was dropped from HEAD
responses. This resulted in certain sites not working correctly with
mod_proxy, such as www.windowsupdate.com. (BZ#506016)
After installing the updated packages, the httpd daemon must be
restarted for the update to take effect.
