Description

Updated CVS packages are now available for CentOS Linux Advanced Server. These updates fix a vulnerability which would permit arbitrary command execution on servers configured to allow anonymous read-only access. [Updated 06 Feb 2003] Added fixed packages for Advanced Workstation 2.1

CVS is a version control system frequently used to manage source code repositories. During an audit of the CVS sources, Stefan Esser discovered an exploitable double-free bug in the CVS server. On servers which are configured to allow anonymous read-only access, this bug could be used by anonymous users to gain write privileges. Users with CVS write privileges can then use the Update-prog and Checkin-prog features to execute arbitrary commands on the server. All users of CVS are advised to upgrade to these packages which contain patches to correct the double-free bug. Our thanks go to Stefan Esser of e-matters for reporting this issue to us.
