HP Security Bulletin HPSBUX02612 SSRT100345 - Potential security vulnerabilities have been identified with HP-UX Apache-based Web Server. These vulnerabilities could be exploited locally to disclose information, increase privilege or remotely create a Denial of Service (DoS). Revision 1 of this advisory.

Packages for 2008.0 are being provided due to extended support for Corporate products. This update provides a solution to these vulnerabilities.
e56a54d6bdc82b29375d1213af66206fb4ca08275ca3ccd4eb0ad21e18bffd71Debian Security Advisory 1834-2 - The previous update caused a regression for apache2 in Debian 4.0 "etch". Using mod_deflate together with mod_php could cause segfaults when a client aborts a connection. This update corrects this flaw. A denial of service flaw was found in the Apache mod_proxy module when it was used as a reverse proxy. A remote attacker could use this flaw to force a proxy process to consume large amounts of CPU time. This issue did not affect Debian 4.0 "etch". 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. A similar flaw related to HEAD requests for compressed content was also fixed.
2bb04b990a52bd709d6c38bea3fd00f71adef9c7a03e217b9679cec6bd703f6dMandriva Linux Security Advisory 2009-168 - The stream_reqbody_cl function in mod_proxy_http.c in the mod_proxy module in the Apache HTTP Server before 2.3.3, when a reverse proxy is configured, does not properly handle an amount of streamed data that exceeds the Content-Length value, which allows remote attackers to cause a denial of service (CPU consumption) via crafted requests. Fix a potential Denial-of-Service attack against mod_deflate or other modules, by forcing the server to consume CPU time in compressing a large file after a client disconnects. This update provides fixes for these vulnerabilities.

A remote attacker could exploit this and cause a denial of service via memory resource consumption. This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04. It was discovered that mod_deflate did not abort compressing large files when the connection was closed. A remote attacker could exploit this and cause a denial of service via CPU resource consumption.
