[Secure-testing-team] Bug#591552: Two security issues

[Moritz Muehlenhoff]

Package: cabextract
Version: 1.2-4
Severity: grave
Tags: security

The following was sent to us by Red Hat:

1, Infinite loop in MS-ZIP and Quantum decoders (minor issue):
(CVE-2010-2800)

A deficiency has been reported in the way cabextract extracted
certain Cabinet (*.cab) files, using the MZ-ZIP and Quantum decompressors.
If a local user was tricked into opening a specially-crafted *.cab
file, it could lead to infinite loop.

2, Integer wrap-around (crash) by processing certain *.cab files in test archive mode
(CVE-2010-2801)

An integer wrap-around flaw has been reported in the way cabextract processed
certain Cabinet (*.cab) archive files. If a local user was tricked into opening
a specially-crafted *.cab archive in test archive mode, it could lead to cabextract
executable crash.

I'll update CVE-2010-2801 for stable-security, CVE-2010-2800 is borderline of a security
issue.

Cheers,
