Squirrelmail fails to properly sanitize user input, which could lead to a compromise of webmail accounts.
|Package||mail-client/squirrelmail on all architectures|
|Affected versions||<= 1.4.3_rc1-r1|
|Unaffected versions||>= 1.4.3|
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:
# emerge sync # emerge -pv ">=mail-client/squirrelmail-1.4.3" # emerge ">=mail-client/squirrelmail-1.4.3"
