- CWE-125 - Out-of-bounds Read
Summary
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Tencent WeChat 2.9.5 desktop version. 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 read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-11907.

CWE
- CWE-356 - Product UI does not Warn User of Unsafe Actions
Summary
This vulnerability allows remote attackers redirect users to an external resource on affected installations of Tencent WeChat Prior to 7.0.9. User interaction is required to exploit this vulnerability in that the target must be within a chat session together with the attacker. The specific flaw exists within the parsing of a users profile. The issue lies in the failure to properly validate a users name. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-9302.
