ID CVE-2005-2970
Summary Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.

    description Updated Apache httpd packages that correct three security issues are now available for Red Hat Enterprise Linux 3 and 4. This update has been rated as having moderate security impact by the Red Hat Security Response Team. The Apache HTTP Server is a popular and freely-available Web server. A memory leak in the worker MPM could allow remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2970 to this issue. This vulnerability only affects users who are using the non-default worker MPM. A flaw in mod_imap when using the Referer directive with image maps was discovered. With certain site configurations, a remote attacker could perform a cross-site scripting attack if a victim can be forced to visit a malicious URL using certain web browsers. (CVE-2005-3352) A NULL pointer dereference flaw in mod_ssl was discovered affecting server configurations where an SSL virtual host is configured with access control and a custom 400 error document. A remote attacker could send a carefully crafted request to trigger this issue which would lead to a crash. This crash would only be a denial of service if using the non-default worker MPM. (CVE-2005-3357) Users of httpd should update to these erratum packages which contain backported patches to correct these issues along with some additional bugs.

    description A memory leak was found in the Apache 2 'worker' module in the handling of aborted TCP connections. By repeatedly triggering this situation, a remote attacker could drain all available memory, which eventually led to a Denial of Service. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description A memory leak in the worker MPM in Apache 2 could allow remote attackers to cause a Denial of Service (memory consumption) via aborted commands in certain circumstances, which prevents the memory for the transaction pool from being reused for other connections. As well, this update addresses two bugs in the Mandriva 2006 Apache packges where apachectl was missing and also a segfault that occured when using the mod_ldap module.

    description The remote host appears to be running a version of Apache that is prior to 2.0.55. It is, therefore affected by multiple vulnerabilities : - A security issue exists where 'SSLVerifyClient' is not enforced in per-location context if 'SSLVerifyClient optional' is configured in the vhost configuration. (CVE-2005-2700) - A denial of service vulnerability exists when processing a large byte range request, as well as a flaw in the 'worker.c' module which could allow an attacker to force this service to consume excessive amounts of memory. (CVE-2005-2970) - When Apache is acting as a proxy, it is possible for a remote attacker to poison the web cache, bypass web application firewall protection, and conduct cross-site scripting attacks via an HTTP request with both a 'Transfer-Encoding: chunked' header and a 'Content-Length' header. (CVE-2005-2088) - Multiple integer overflows exists in PCRE in quantifier parsing which could be triggered by a local user through use of a specially crafted regex in an .htaccess file. (CVE-2005-2491) - An issue exists where the byte range filter buffers responses into memory. (CVE-2005-2728) - An off-by-one overflow exists in mod_ssl while printing CRL information at 'LogLevel debug' which could be triggered if configured to use a 'malicious CRL'. (CVE-2005-1268)
