Maildrop: privilege escalation

Maildrop: privilege escalation Insecure permission handling in maildrop might allow local attackers to elevate their privileges. maildrop 2010-09-06 2010-09-06 308043 local 2.4.2 2.4.2

maildrop is the mail filter/mail delivery agent that is used by the Courier Mail Server.

Christoph Anton Mitterer reported that maildrop does not properly drop its privileges when run as root.

A local attacker could create a specially crafted .mailfilter file, possibly leading to the execution of arbitrary commands with the "root" group privileges. NOTE: Successful exploitation requires that maildrop is run as root with the -d option.

There is no known workaround at this time.

All maildrop users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-filter/maildrop-2.4.2"
