Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-4019

James Bercegay of GulfTech Security Research disovered a vulnerability
in SquirrelMail where an authenticated user could overwrite random
variables in the compose script. This might be exploited to read or
write the preferences or attachment files of other users.

For the stable distribution (sarge) this problem has been fixed in
version 1.4.4-9.

For the unstable distribution (sid) this problem has been fixed in
version 1.4.8-1.

We recommend that you upgrade your squirrelmail package.
