Vulnerability details
The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.
The vulnerability exists due to integer overflow and underflow in the ASF demuxer when parsing crafted ASF, WMV, or WMA files. A remote attacker can provide a specially crafted media file to disclose sensitive information and cause a denial of service.
Merely opening or previewing a crafted file is sufficient to trigger the vulnerability, and over-read data may be incorporated into media metadata tags, enabling limited heap information leakage.
