Debian GNU/Linux Advisory: cvs

The account management of the CVS pserver (which is used to give
remote access to CVS repositories) uses a CVSROOT/passwd file in
each repository which contains the accounts and their
authentication information as well as the name of the local unix
account to use when a pserver account is used. Since CVS performed
no checking on what unix account was specified anyone who could
modify the CVSROOT/passwd could gain access to all local users on
the CVS server, including root.

This has been fixed in upstream version 1.11.11 by preventing
pserver from running as root. For Debian this problem is solved in
version 1.11.1p1debian-9 in two different ways:

• pserver is no longer allowed to use root to access
  repositories
• a new /etc/cvs-repouid is introduced which can be used by the
  system administrator to override the unix account used to access a
  repository. More information on this change can be found at
  http://www.wiggy.net/code/cvs-repouid/

Additionaly, CVS pserver had a bug in parsing module requests
which could be used to create files and directories outside a
repository. This has been fixed upstream in version 1.11.11 and
Debian version 1.11.1p1debian-9.

Finally, the umask used for ‘cvs init’ and ‘cvs-makerepos’ has
been changed to prevent repositories from being created with group
write permissions.
