GLSA-200410-31 : Archive::Zip: Virus detection evasion

This script is Copyright (C) 2004-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200410-31
(Archive::Zip: Virus detection evasion)

Archive::Zip can be used by email scanning software (like amavisd-new)
to uncompress attachments before virus scanning. By modifying the
uncompressed size of archived files in the global header of the ZIP
file, it is possible to fool Archive::Zip into thinking some files
inside the archive have zero length.

Impact :

An attacker could send a carefully crafted ZIP archive containing a
virus file and evade detection on some email virus-scanning software
relying on Archive::Zip for decompression.

Workaround :

There is no known workaround at this time.

Solution :

All Archive::Zip users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-perl/Archive-Zip-1.14'

Risk factor :

High / CVSS Base Score : 7.5
