Description
Two vulnerabilities have been reported in various CA products, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An input validation error when processing CHM files can be exploited to cause an infinite loop via a specially crafted CHM file with an invalid 'previous listing chunk number' field.
