Gentoo Linux Security Advisory

Title: Squirrelmail: Another XSS vulnerability (GLSA 200406-08)
Severity: normal
Exploitable: remote
Date: June 15, 2004
Updated: May 22, 2006
Bug(s): #52434
ID: 200406-08

Synopsis

Squirrelmail fails to properly sanitize user input, which could lead to a compromise of webmail accounts.

Background

SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP, and can optionally be installed with SQL support.

Affected Packages

Package: mail-client/squirrelmail
Vulnerable: <= 1.4.3_rc1-r1
Unaffected: >= 1.4.3
Architectures: All supported architectures


Description

A new cross-site scripting (XSS) vulnerability in Squirrelmail-1.4.3_rc1 has been discovered. In functions/mime.php Squirrelmail fails to properly sanitize user input.

Impact

By enticing a user to read a specially crafted e-mail, 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 stable version:
Code:
# emerge sync
# emerge -pv ">=mail-client/squirrelmail-1.4.3"
# emerge ">=mail-client/squirrelmail-1.4.3"
