CVE-2014-0117

The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header.

A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module (MPM) could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the "apache" user (CVE-2014-0226).

A denial of service flaw was found in the mod_proxy httpd module. A remote attacker could send a specially crafted request to a server configured as a reverse proxy using a threaded Multi-Processing Modules (MPM) that would cause the httpd child process to crash (CVE-2014-0117).

A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the "DEFLATE" input filter). A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system (CVE-2014-0118).

A denial of service flaw was found in the way httpd's mod_cgid module executed CGI scripts that did not read data from the standard input. A remote attacker could submit a specially crafted request that would cause the httpd child process to hang indefinitely (CVE-2014-0231).

These are all security issues fixed in the apache2-2.4.23-4.1 package on the GA media of openSUSE Tumbleweed.

The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header.

Marek Kroemeke discovered that the mod_proxy module incorrectly handled certain requests. A remote attacker could use this issue to cause the server to stop responding, leading to a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0117)

Giancarlo Pellegrino and Davide Balzarotti discovered that the mod_deflate module incorrectly handled body decompression. A remote attacker could use this issue to cause resource consumption, leading to a denial of service. (CVE-2014-0118)

Marek Kroemeke and others discovered that the mod_status module incorrectly handled certain requests. A remote attacker could use this issue to cause the server to stop responding, leading to a denial of service, or possibly execute arbitrary code. (CVE-2014-0226)

Rainer Jung discovered that the mod_cgid module incorrectly handled certain scripts. A remote attacker could use this issue to cause the server to stop responding, leading to a denial of service. (CVE-2014-0231)
