VERIFY ADVISORY:
http://secunia.com/advisories/27458/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
Perdition 1.x
http://secunia.com/product/13400/

DESCRIPTION:
Bernhard Mueller has reported a vulnerability in Perdition, which can
be exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

The vulnerability is caused due to the Perdition IMAP server
incorrectly checking for malicious format string specifiers contained
within IMAP requests. This can be exploited to bypass the format
string check by inserting a zero byte in an IMAP request.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in versions prior to 1.17.1.

SOLUTION:
Update to version 1.17.1.
