Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

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.
