Description
Description by Zero Day Initiative via the CVE Program.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Xiaomi Mi6 Browser prior to 10.4.0. 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 WebAssembly.Instance method. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-7466.
