Title:	SquirrelMail: Several XSS vulnerabilities
Date:	06/21/2005
Bugs:	#95937
ID:	200506-19

Synopsis

Squirrelmail is vulnerable to several cross-site scripting vulnerabilities which could lead to a compromise of webmail accounts.

Background

SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP protocols.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-client/squirrelmail	< 1.4.4	>= 1.4.4	All supported architectures

Description

SquirrelMail is vulnerable to several cross-site scripting issues, most reported by Martijn Brinkers.

Impact

By enticing a user to read a specially-crafted e-mail or using a manipulated URL, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc.

Workaround

There is no known workaround at this time.

Resolution

All SquirrelMail users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.4"

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
