The email gateway in RT (aka Request Tracker) 3.0.0 through 4.x before 4.0.23 and 4.2.x before 4.2.10 allows remote attackers to cause a denial of service (CPU and disk consumption) via a crafted email.
The MobileUI (aka RT-Extension-MobileUI) extension before 1.04 in Request Tracker (RT) 4.0.0 before 4.0.13, when using the file-based session store (Apache::Session::File) and certain authentication extensions, allows remote attackers to reuse unauthorized sessions and obtain user preferences and caches via unspecified vectors.
Algorithmic complexity vulnerability in Email::Address::List before 0.02, as used in RT 4.2.0 through 4.2.2, allows remote attackers to cause a denial of service (CPU consumption) via a string without an address.
Cross-site scripting (XSS) vulnerability in the MobileUI (aka RT-Extension-MobileUI) extension before 1.04 in Request Tracker (RT) 4.0.0 before 4.0.13 allows remote attackers to inject arbitrary web script or HTML via the name of an attached file.
bin/rt in Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows local users to overwrite arbitrary files via a symlink attack on a temporary file with predictable name.
Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows remote authenticated users with the permissions to view the administration pages to execute arbitrary private components via unspecified vectors.
Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 does not properly restrict access to private callback components, which allows remote attackers to have an unspecified impact via a direct request.
Cross-site scripting (XSS) vulnerability in Request Tracker (RT) 3.8.3 through 3.8.16 and 4.0.x before 4.0.13 allows remote attackers to inject arbitrary web script or HTML via the filename of an attachment.
Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows remote attackers to inject multiple Content-Disposition HTTP headers and possibly conduct cross-site scripting (XSS) attacks via unspecified vectors.
CRLF injection vulnerability in Request Tracker (RT) 3.8.x before 3.8.17 and 4.0.x before 4.0.13 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a MIME header.
