  script_tag(name:"insight", value:"The Concurrent Versions System (CVS) is a version control system.  It
may be used to access a repository locally, or to access a `remote
repository' using a number of different methods.  When accessing a
remote repository, the target machine runs the CVS server to fulfill
client requests.

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.");
