Detail
| The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk Multi-Processing Module 2.2.11-01 and 2.2.11-02 for the Apache HTTP Server does not properly handle certain configuration sections that specify NiceValue but not AssignUserID, which might allow remote attackers to gain privileges by leveraging the root uid and root gid of an mpm-itk process. |

| Title: | USN-1259-1 -- Apache vulnerabilities | ||
| Description: | apache2: Apache HTTP server - apache2-mpm-itk: multiuser MPM for Apache 2.2 Details: It was discovered that the mod_proxy module in Apache did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. Stefano Nichele discovered that the mod_proxy_ajp module in Apache when used with mod_proxy_balancer in certain configurations could allow remote attackers to cause a denial of service via a malformed HTTP request. Samuel Montosa discovered that the ITK Multi-Processing Module for Apache did not properly handle certain configuration sections that specify NiceValue but not AssignUserID, preventing Apache from dropping privileges correctly. This issue only affected Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. USN 1199-1 fixed a vulnerability in the byterange filter of Apache. The upstream patch introduced a regression in Apache when handling specific byte range requests. This update fixes the issue. Original advisory Multiple vulnerabilities and a regression were fixed in the Apache HTTP server. | ||
