All supported architectures
Squirrelmail fails to properly sanitize user input, which could lead to a
compromise of webmail accounts.
SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP, and can optionally be installed with SQL support.
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.
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.
There is no known workaround at this time.
All SquirrelMail users should upgrade to the latest stable version:
Code Listing 3.1: Resolution
# emerge sync
# emerge -pv ">=mail-client/squirrelmail-1.4.3"
# emerge ">=mail-client/squirrelmail-1.4.3"
