MDKSA-2003:009 - Updated cvs packages fix multiple vulnerabilities

by Nikola Strahija on January 23rd, 2003 This update fixes the double free() vulnerability and removes the Checkin-prog and Update-prog commands from CVS.

Package name: cvs
Advisory ID: MDKSA-2003:009
Date: January 20th, 2003

Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0,
Single Network Firewall 7.2

Problem Description:

Two vulnerabilities were discoverd by Stefen Esser in the cvs program.
The first is an exploitable double free() bug within the server, which
can be used to execute arbitray code on the CVS server. To accomplish
this, the attacker must have an anonymous read-only login to the CVS
server. The second vulnerability is with the Checkin-prog and
Update-prog commands. If a client has write permission, he can use
these commands to execute programs outside of the scope of CVS, the
output of which will be sent as output to the client.

This update fixes the double free() vulnerability and removes the
Checkin-prog and Update-prog commands from CVS.
