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.

2) An unspecified error when processing RAR archives can be exploited to cause the application to hang when e.g. scanning a specially crafted RAR archive.
