Title: SquirrelMail: Encoded text XSS vulnerability (GLSA 200411-25)
Date: November 17, 2004
Updated: May 22, 2006
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.
Vulnerable: < 1.4.3a-r2
Unaffected: >= 1.4.3a-r2
Architectures: All supported architectures
SquirrelMail fails to properly sanitize certain strings when decoding specially-crafted headers.
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 version:
Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
|# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.3a-r2"
