What is CVE-2019-6740?

A vulnerability in the ASN.1 parser of Samsung Galaxy S9 devices allows remote attackers to execute arbitrary code by persuading users to visit malicious web pages or open harmful files. The flaw arises from improper validation of the length of user-provided ASN.1 strings, which can lead to buffer overflow and code execution in the context of the current process. Users are advised to apply the January 2019 Security Update to mitigate this risk.
