Summary
Red Hat Security Advisory: : : : Updated CVS packages available
Notes
Topic
Updated cvs packages are now available for Red Hat Linux 6.2, 7, 7.1, 7.2,
7.3, and 8.0. These updates close a vulnerability which would permit
arbitrary command execution on servers configured to allow anonymous
read-only access.
[Updated 16 April 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems
Details
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 erratum 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.
