medium Nessus Plugin ID 40632

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200908-07 (Perl Compress::Raw modules: Denial of Service)

Leo Bergolth reported an off-by-one error in the inflate() function in Zlib.xs of Compress::Raw::Zlib, possibly leading to a heap-based buffer overflow (CVE-2009-1391).
Paul Marquess discovered a similar vulnerability in the bzinflate() function in Bzip2.xs of Compress::Raw::Bzip2 (CVE-2009-1884).
Impact :

A remote attacker might entice a user or automated system (for instance running SpamAssassin or AMaViS) to process specially crafted files, possibly resulting in a Denial of Service condition.
Workaround :

There is no known workaround at this time.

Solution

All Compress::Raw::Zlib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=perl-core/Compress-Raw-Zlib-2.020' All Compress::Raw::Bzip2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=perl-core/Compress-Raw-Bzip2-2.020'
