Technical details

A heap-based buffer overflow (CWE-122) exists in Samsung's Escargot JavaScript engine at commit 97e8115. The vulnerability allows for an out-of-bounds write, which can be leveraged by an attacker to corrupt memory. According to the vendor's CVSS assessment, the attack vector is local with high complexity, suggesting specific conditions or local access are required to trigger the overflow. Successful exploitation could lead to arbitrary code execution or a denial-of-service condition. A fix appears to have been addressed in pull request #1554 on the project's GitHub repository.
