Synopsis
Insecure permission handling in maildrop might allow local attackers to elevate their privileges.
Background
maildrop is the mail filter/mail delivery agent that is used by the Courier Mail Server.
Affected Packages
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-filter/maildrop < 2.4.2 >= 2.4.2
Impact
===== 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.
Workaround
There is no known workaround at this time.
