Title: CVS: additional DoS and arbitrary code execution vulnerabilities (GLSA 200406-06)
Date: June 10, 2004
Several serious new vulnerabilities have been found in CVS, which may allow an attacker to remotely compromise a CVS server.
CVS (Concurrent Versions System) is an open-source network-transparent version control system. It contains both a client utility and a server.
Vulnerable: <= 1.11.16-r1
Unaffected: >= 1.11.17
Architectures: All supported architectures
A team audit of the CVS source code performed by Stefan Esser and Sebastian Krahmer resulted in the discovery of several remotely exploitable vulnerabilities including:
- no-null-termination of "Entry" lines
- error_prog_name "double-free()"
- Argument integer overflow
- serve_notify() out of bounds writes
An attacker could use these vulnerabilities to cause a Denial of Service or execute arbitrary code with the permissions of the user running cvs.
There is no known workaround at this time. All users are advised to upgrade to the latest available version of CVS.
All CVS users should upgrade to the latest stable version:
|# emerge sync
# emerge -pv ">=dev-util/cvs-1.11.17"
# emerge ">=dev-util/cvs-1.11.17"
