Description Josh Bressers 2005-07-01 20:52:11 UTC
A new vulnerability has been discovered in SquirrelMail. The file
src/options_identities.php contained some very bad, legacy code: an
extract($_POST) was done, effectively allowing a malicious attacker to
change session variables and even other people's preferences.

It must be noted that for this to happen you need to trick someone into
using an external form to post the information which is not trivial.
