[原文]Multiple integer overflows in MPlayer 1.0pre7try2 allow remote attackers to cause a denial of service and trigger heap-based buffer overflows via (1) a certain ASF file handled by asfheader.c that causes the asf_descrambling function to be passed a negative integer after the conversion from a char to an int or (2) an AVI file with a crafted wLongsPerEntry or nEntriesInUse value in the indx chunk, which is handled in aviheader.c.

MPlayer libmpdemux/asfheader.c asf_descrambling() Function ASF Processing Overflow
Remote / Network Access Input Manipulation
Loss of Integrity, Loss of Availability

- 漏洞描述

A remote overflow exists in MPlayer. MPlayer fails to properly handle a specially crafted ASF file in 'libmpdemux/asfheader.c' resulting in a integer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity and/or availability.

- 漏洞讨论

MPlayer is susceptible to two integer-overflow vulnerabilities. An attacker may exploit these issues to execute arbitrary code with the privileges of the user that activated the vulnerable application. This may help the attacker gain unauthorized access or escalate privileges.

MPlayer version 1.0.20060329 is affected by these issues; other versions may also be affected.
