CVE-2016-1963

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 45.0

Description The issue is related to the FileReader class in Mozilla Firefox, which has insufficient access control. This can be exploited by a local attacker to gain privileges or cause a denial of service (memory corruption) by changing a file during a FileReader API read operation.

Recommendations For versions prior to 45.0, update to version 45.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the FileReader API until a patch is available.
