TITLE:
Network Security Services Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA36093

VERIFY ADVISORY:
http://secunia.com/advisories/36093/

DESCRIPTION:
Some vulnerabilities have been reported in Network Security Services,
which can potentially be exploited by malicious people to bypass
certain security restrictions or to compromise a vulnerable system.

1) An error in the regular expression parser when matching common
names in certificates can be exploited to cause a heap-based buffer
overflow, e.g. via a specially crafted certificate signed by a
trusted CA or when a user accepts a specially crafted certificate.

Successful exploitation may allow execution of arbitrary code.

2) An error exists in the parsing of certain certificate fields,
which can be exploited to e.g. get a client to accept a specially
crafted certificate by mistake.

SOLUTION:
Update to version 3.12.3 or later.
