Description The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. It is also described as a buffer data boundary operation issue, where exploitation could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
