A possible arbitrary memory overwrite vulnerabilities in quram library version prior to SMR Jan-2021 Release 1 allow arbitrary code execution.

Una posible vulnerabilidad de sobrescritura de memoria arbitraria en la biblioteca quram versión anterior a SMR Jan-2021 Release 1, permite una ejecución de código arbitraria

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Samsung Galaxy S20. 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 Quram ImageCodec component. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
