Mozilla · Firefox · CVE-2020-12426
**Name of the Vulnerable Software and Affected Versions**
Firefox versions prior to 78
**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.
**Recommendations**
For versions prior to 78, update to version 78 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and implementing additional security measures to minimize the risk of exploitation.
