Microsoft Windows Media Player ASX playlist buffer overflow
| windowsmedia-asxplaylist-bo (30586) |  High Risk |
Description:
Windows Media Player is vulnerable to a heap-based buffer overflow in the WMVCORE.DLL library, caused by improper bounds checking of "REF HREF" URLs in Advanced Stream Redirector (.ASX) files. By creating a malformed ASX file and persuading a victim to open the file, a remote attacker could overflow a buffer and cause the application to crash or execute arbitrary code on the system with the privileges of the victim. An attacker could exploit this vulnerability by hosting the malicious file on a Web site or sending it as an email attachment.
