Debian Testing Security Advisory DTSA-11-1 http://secure-testing.debian.net

Package : maildrop
Vulnerability : local privilege escalation
Problem-Type : local
Debian-specific: yes
CVE ID : CAN-2005-2655
The lockmail binary shipped with maildrop allows for an attacker to
obtain an effective gid as group "mail". Debian ships the binary with its
setgid bit set, but the program does not drop privileges when run. It takes
an argument that is executed, and since it does not drop privileges, an
attacker can execute an arbitrary command with an effective gid of the "mail"
group.
For the testing distribution (etch) this is fixed in version
1.5.3-1.1etch1.
For the unstable distribution (sid) this is fixed in version
1.5.3-2.
This upgrade is strongly recommended if you use maildrop.
The Debian testing security team does not track security issues for the
stable distribution (woody). If stable is vulnerable, the Debian security
team will make an announcement once a fix is ready.
