TITLE:
maildrop Privilege Escalation Security Issue

SECUNIA ADVISORY ID:
SA38367

VERIFY ADVISORY:
http://secunia.com/advisories/38367/

DESCRIPTION:
A security issue has been reported in maildrop, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issue is caused due to maildrop not properly setting up
supplementary groups, which can be exploited to perform certain
actions with e.g. "root" group privileges.

Successful exploitation requires that maildrop is compiled without
"RESET_GID" being set (e.g. if the mail directory does not use the
sticky bit).

SOLUTION:
Fixed in the CVS repository.
