Heap-based buffer overflow in the proxy_connect function in src/client.c in CVS 1.11 and 1.12 allows remote HTTP proxy servers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted HTTP response.
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.
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.
CVS 1.12 and earlier on Debian GNU/Linux does not properly handle when a mapping for the current repository does not exist in the cvs-repouids file, which allows remote attackers to cause a denial of service (server crash).
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.
Integer overflow in the "Max-dotdot" CVS protocol command (serve_max_dotdot) 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.
serve_notify 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.
Double free vulnerability for the error_prog_name 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 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.
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.
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.
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.
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.
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.
