Detailsinfo

A vulnerability, which was classified as critical, was found in Samsung Galaxy S9 (Smartphone Operating System) (the affected version unknown). Affected is an unknown part of the component ASN.1 Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S9 prior to January 2019 Security Update (SMR-JAN-2019 - SVE-2018-13467). 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 ASN.1 parser. When parsing ASN.1 strings, the process 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 vulnerability to execute code in the context of the current process. Was ZDI-CAN-7472.

The bug was discovered 03/05/2019. The weakness was shared 06/03/2019. This vulnerability is traded as CVE-2019-6740 since 01/24/2019. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.

The vulnerability was handled as a non-public zero-day exploit for at least 90 days. During that time the estimated underground price was around $0-$5k.

Applying the patch SMR-JAN-2019 - SVE-2018-13467 is able to eliminate this problem.
