Varnish before 3.0.5 allows remote attackers to cause a denial of service (child-process crash and temporary caching outage) via a GET request with trailing whitespace characters and no URI.

The Memcache module 5.x before 5.x-1.10 and 6.x before 6.x-1.6 for Drupal does not properly handle the $user object in memcache_admin, which might "lead to a role change not being recognized until the user logs in again."

Cross-site scripting (XSS) vulnerability in memcache_admin in the Memcache module 5.x before 5.x-1.10 and 6.x before 6.x-1.6 for Drupal allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site scripting (XSS) vulnerability in apc.php in the Alternative PHP Cache (APC) extension before 3.1.4 for PHP allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

memcached.c in memcached before 1.4.3 allows remote attackers to cause a denial of service (daemon hang or crash) via a long line that triggers excessive memory allocation. NOTE: some of these details are obtained from third party information.

vccleaner in VideoCache 1.9.2 allows local users with Squid proxy user privileges to overwrite arbitrary files via a symlink attack on /var/log/videocache/vccleaner.log.

Multiple cross-site scripting (XSS) vulnerabilities in the ImageCache module 5.x before 5.x-2.5 and 6.x before 6.x-2.0-beta10, a module for Drupal, allow remote authenticated users, with "administer imagecache" permissions, to inject arbitrary web script or HTML via unspecified vectors.

The ImageCache module 5.x before 5.x-2.5 and 6.x before 6.x-2.0-beta10, a module for Drupal, when the private file system is used, does not properly perform access control for derivative images, which allows remote attackers to view arbitrary images via a request that specifies an image's filename.

Multiple integer overflows in memcached 1.1.12 and 1.2.2 allow remote attackers to execute arbitrary code via vectors involving length attributes that trigger heap-based buffer overflows.

The process_stat function in (1) Memcached before 1.2.8 and (2) MemcacheDB 1.2.0 discloses (a) the contents of /proc/self/maps in response to a stats maps command and (b) memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain sensitive information such as the locations of memory regions, and defeat ASLR protection, by sending a command to the daemon's TCP port.
