CVE-2019-6740

Name of the Vulnerable Software and Affected Versions Samsung Galaxy S9 versions prior to January 2019 Security Update

Description This issue allows remote attackers to execute arbitrary code on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The specific flaw exists within the ASN.1 parser, which does not properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this to execute code in the context of the current process.

Recommendations For Samsung Galaxy S9 versions prior to January 2019 Security Update, apply the January 2019 Security Update (SMR-JAN-2019 - SVE-2018-13467) to resolve the issue. As a temporary workaround, consider restricting user interaction with potentially malicious pages or files until the update is applied.
