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.
