SquirrelMail: Several XSS vulnerabilities — GLSA 200506-19

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

Affected Packages

mail-client/squirrelmail on all architectures
Affected versions < 1.4.4
Unaffected versions >= 1.4.4, < 1.4.0

Background

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

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.
