http://security.gentoo.org/

Severity:	low
Title:	MIME-tools: Virus detection evasion
Date:	11/02/2004
Bugs:	#69181
ID:	200411-06

Synopsis

MIME-tools doesn't handle empty MIME boundaries correctly. This may prevent some virus-scanning programs which use MIME-tools from detecting certain viruses.

Background

MIME-tools is a Perl module containing functions to handle MIME attachments.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-perl/MIME-tools	< 5.415	>= 5.415	All supported architectures

Description

MIME-tools doesn't correctly parse attachment boundaries with an empty name (boundary="").

Impact

An attacker could send a carefully crafted email and evade detection on some email virus-scanning programs using MIME-tools for attachment decoding.

Workaround

There is no known workaround at this time.

Resolution

All MIME-tools users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-perl/MIME-tools-5.415"
