Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

A number of vulnerabilities were discovered in CVS by Stefan Esser,
Sebastian Krahmer, and Derek Price.

- Insufficient input validation while processing 'Entry' lines.
(CVE-2004-0414)

- A double-free resulting from erroneous state handling while
processing 'Argumentx' commands. (CVE-2004-0416)

- Integer overflow while processing 'Max-dotdot' commands.
(CVE-2004-0417)

- Erroneous handling of empty entries handled while processing
'Notify' commands. (CVE-2004-0418)

- A format string bug while processing CVS wrappers.

- Single-byte buffer underflows while processing configuration files
from CVSROOT.

- Various other integer overflows.

Additionally, iDEFENSE reports an undocumented command-line flag used
in debugging does not perform input validation on the given path
names.

CVS servers ('cvs server' or :pserver: modes) are affected by these
vulnerabilities. They vary in impact but include information
disclosure (the iDEFENSE-reported bug), denial-of-service
(CVE-2004-0414, CVE-2004-0416, CVE-2004-0417 and other bugs), or
possibly arbitrary code execution (CVE-2004-0418). In very special
situations where the attacker may somehow influence the contents of
CVS configuration files in CVSROOT, additional attacks may be
possible.
