"VMnc media codec is installed on the remote host. The codec is
typically installed along with VMware Workstation, VMware Player,
VMware ACE or in its standalone configuration by installing VMware
Workstation Movie Decoder and is required to play movies recorded with
VMware applications.

The installed version is affected by multiple heap-based buffer
overflow vulnerabilities. By tricking an user into opening a specially
crafted video file with incorrect framebuffer parameters, an attacker
may be able to exploit these vulnerabilities to trigger a denial of
service condition or execute arbitrary code on the remote system.");
