This is very obscure and is limited only to valid users within your
squirrelmail application (e.g. the person has to have a valid login in
order to exploit this vulnerability). The problem is fixed in the
current CVS and will be out with Squirrelmail-1.2.6. Here is the fix,
should you want to apply it, or just wait till the next release, since
this is not a high-risk vulnerability.

Konstantin Riabitsev,
