CVS server before 1.11.10 may allow attackers to cause the CVS server to create directories and files in the file system root directory via malformed module requests.

Double-free vulnerability in CVS 1.11.4 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed Directory request, as demonstrated by bypassing write checks to execute Update-prog and Checkin-prog commands.

Concurrent Versions Software (CVS) uses predictable temporary file names for locking, which allows local users to cause a denial of service by creating the lock directory before it is created for use by a legitimate CVS user.

CVS 1.12 and earlier on Debian GNU/Linux, when using the repouid patch, allows remote attackers to bypass authentication via the pserver access method.

The CVS 1.10.8 client trusts pathnames that are provided by the CVS server, which allows the server to force the client to create arbitrary files.

The CVS 1.10.8 server does not properly restrict users from creating arbitrary Checkin.prog or Update.prog programs, which allows remote CVS committers to modify or create Trojan horse programs with the Checkin.prog or Update.prog names, then performing a CVS commit action.

CVS before 1.10.8 does not properly initialize a global variable, which allows remote attackers to cause a denial of service (server crash) via the diff capability.

Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line.

CVS 1.11.x before 1.11.17, and 1.12.x before 1.12.9, allows remote attackers to determine the existence of arbitrary files and directories via the -X command for an alternate history file, which causes different error messages to be returned.

Double free vulnerability for the errorprogname string in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to execute arbitrary code.

CVS before 1.11 allows CVS clients to read arbitrary files via .. (dot dot) sequences in filenames via CVS client requests, a different vulnerability than CVE-2004-0180.

Integer overflow in the "Max-dotdot" CVS protocol command (servemaxdotdot) for CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, may allow remote attackers to cause a server crash, which could cause temporary data to remain undeleted and consume disk space.

CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle malformed "Entry" lines, which prevents a NULL terminator from being used and may lead to a denial of service (crash), modification of critical program data, or arbitrary code execution.

Heap-based buffer overflow in CVS 1.11.x up to 1.11.15, and 1.12.x up to 1.12.7, when using the pserver mechanism allows remote attackers to execute arbitrary code via Entry lines.

servenotify in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle empty data lines, which may allow remote attackers to perform an "out-of-bounds" write for a single byte to execute arbitrary code or modify critical program data.

The client for CVS before 1.11 allows a remote malicious CVS server to create arbitrary files using certain RCS diff files that use absolute pathnames during checkouts or updates, a different vulnerability than CVE-2004-0405.

cvsbug in CVS 1.12.12 and earlier creates temporary files insecurely, which allows local users to overwrite arbitrary files and execute arbitrary code via a symlink attack.

Buffer overflow in CVS before 1.11.20 allows remote attackers to execute arbitrary code.
