AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Tencent WeChat. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the WXAM Decoder. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
