The virBitmapParse function in util/virbitmap.c in libvirt before 1.1.2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via a crafted bitmap, as demonstrated by a large nodeset value to numatune.

The remoteDispatchStoragePoolListAllVolumes function in the storage pool manager in libvirt 1.0.5 allows remote attackers to cause a denial of service (file descriptor consumption) via a large number of requests "to list all volumes for the particular pool."

Multiple cross-site request forgery (CSRF) vulnerabilities in Best Practical Solutions RT before 3.8.12 and 4.x before 4.0.6 allow remote attackers to hijack the authentication of arbitrary users.

Best Practical Solutions RT before 3.8.9 does not perform certain redirect actions upon a login, which allows physically proximate attackers to obtain credentials by resubmitting the login form via the back button of a web browser on an unattended workstation after an RT logout.

Scrips_Overlay.pm in Best Practical Solutions RT before 3.8.9 does not properly restrict access to a TicketObj in a Scrip after a CurrentUser change, which allows remote authenticated users to obtain sensitive information via unspecified vectors, as demonstrated by custom-field value information, related to SQL logging.
