Description:
Fabian Becker has reported a vulnerability 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.*.94 through 1.0.*.98.
