Slackware: cvs Arbitrary file creation vulnerabilities
Posted by LinuxSecurity.com Team   
Slackware Two seperate cvs vulnerabilities, one for the client and one for the server, allow the creation of files at arbitrary paths.

[slackware-security]  cvs security update (SSA:2004-108-02)

CVS is a client/server version control system.  As a server, it
is used to host source code repositories.  As a client, it is
used to access such repositories.  This advisory affects both uses
of CVS.

A security problem which could allow a server to create arbitrary
files on a client machine, and another security problem which may
allow a client to view files outside of the CVS repository have
been fixed with the release of cvs-1.11.15.

Any sites running CVS should upgrade to the new CVS package.


Here are the details from the Slackware 9.1 ChangeLog:
