CRITICAL:

IMPACT:
Unknown, DoS, System access

WHERE:

SOFTWARE:
Concurrent Versions System (CVS) 1.x
http://secunia.com/product/974/

DESCRIPTION:
Multiple vulnerabilities have been reported in CVS, where one has an
unknown impact and others which potentially can be exploited by
malicious people to cause a DoS (Denial of Service) and compromise a
vulnerable system.

1) An unspecified boundary error can be exploited to cause a buffer
overflow and potentially execute arbitrary code.

2) Some memory leaks and NULL pointer dereferences may be exploited
to cause a DoS.

3) An unspecified error caused due to an arbitrary free has an
unknown impact.

4) Some errors in the contributed Perl scripts can be exploited to
execute arbitrary code via a malicious Perl library.

Successful exploitation requires that the user has commit access and
that one of the contributed Perl scripts has been installed
improperly.

SOLUTION:
Update to version 1.11.20.
