Apache 1.3: Multiple vulnerabilities1. Gentoo Linux Security Advisory
Related bugreports: #51815 Several security vulnerabilites have been fixed in the latest release of Apache 1.3. The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems. The goal of this project is to provide a secure, efficient and extensible server that provides services in tune with the current HTTP standards. On 64-bit big-endian platforms, mod_access does not properly parse Allow/Deny rules using IP addresses without a netmask which could result in failure to match certain IP addresses. Terminal escape sequences are not filtered from error logs. This could be used by an attacker to insert escape sequences into a terminal emulater vulnerable to escape sequences. mod_digest does not properly verify the nonce of a client response by using a AuthNonce secret. This could permit an attacker to replay the response of another website. This does not affect mod_auth_digest. On certain platforms there is a starvation issue where listening sockets fails to handle short-lived connection on a rarely-accessed listening socket. This causes the child to hold the accept mutex and block out new connections until another connection arrives on the same rarely-accessed listening socket thus leading to a denial of service. These vulnerabilities could lead to attackers bypassing intended access restrictions, denial of service, and possibly execution of arbitrary code. There is no known workaround at this time. All users should upgrade to the latest stable version of Apache 1.3.
