DESCRIPTION:
A vulnerability has been reported in Skype, which can be exploited by
malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the
handling of command line arguments. This can be exploited to cause a
stack-based buffer overflow by e.g. tricking a user into visiting a
malicious web site, which passes an overly long string (more than
4096 bytes) to the "callto:" URI handler.
Successful exploitation may allow execution of arbitrary code.
The vulnerability affects versions 1.0.*.95 through 1.0.*.98.
SOLUTION:
Update to version 1.0.0.100.
