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
Description ===========
Christoph Anton Mitterer reported that maildrop does not properly drop its privileges when run as root.
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.
Resolution ==========
All maildrop users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-filter/maildrop-2.4.2"
References ==========
