DESCRIPTION:
Multiple vulnerabilities have been reported in Ethereal, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
compromise a vulnerable system.

The vulnerabilities are caused due to various types of errors
including boundary errors, an off-by-one error, an infinite loop
error, and several unspecified errors in a multitude of protocol
dissectors.

Successful exploitation causes Ethereal to stop responding, consume a
large amount of system resources, crash, or execute arbitrary code.

The vulnerabilities affect versions 0.8.5 through 0.10.14.

SOLUTION:
Upgrade to version 0.99.0
