TITLE:
MasqMail Two Privilege Escalation Vulnerabilities

SECUNIA ADVISORY ID:
SA16883

VERIFY ADVISORY:
http://secunia.com/advisories/16883/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
MasqMail 0.x
http://secunia.com/product/5738/

DESCRIPTION:
Jens Steube has reported two vulnerabilities in MasqMail, which
potentially can be exploited by malicious, local users to gain
escalated privileges.

1) An error in the sanitization of email addresses when the sending
of a message fails, may be exploited to execute arbitrary commands
with privileges of the mail user.

2) An unspecified error in the handling of log files may be exploited
to overwrite arbitrary files via a symlink attack.

SOLUTION:
Grant only trusted users access to affected systems.

Some Linux vendors have released fixed packages.
