http://security.gentoo.org/

Severity:	normal
Title:	Sylpheed, Sylpheed-claws: Message reply overflow
Date:	03/20/2005
Bugs:	#84056
ID:	200503-26

Synopsis

Sylpheed and Sylpheed-claws contain a vulnerability that can be triggered when replying to specially crafted messages.

Background

Sylpheed is a lightweight email client and newsreader. Sylpheed-claws is a 'bleeding edge' version of Sylpheed.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-client/sylpheed	< 1.0.3	>= 1.0.3	All supported architectures
mail-client/sylpheed-claws	< 1.0.3	>= 1.0.3	All supported architectures

Description

Sylpheed and Sylpheed-claws fail to properly handle non-ASCII characters in email headers when composing reply messages.

Impact

An attacker can send an email containing a malicious non-ASCII header which, when replied to, would cause the program to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the software.

Workaround

There is no known workaround at this time.

Resolution

All Sylpheed users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-1.0.3"

All Sylpheed-claws users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.3"
