Name of the Vulnerable Software and Affected Versions:
Firefox versions prior to 58
Description:
A heap buffer overflow issue may occur in WebAssembly when
shrinkElements is called followed by garbage collection on memory that is now uninitialized, resulting in a potentially exploitable crash. The vulnerability can be exploited by a remote attacker to cause a denial of service.Recommendations:
For versions prior to 58, update to version 58 or later to resolve the issue. As a temporary workaround, consider disabling WebAssembly until a patch is available. Restrict access to WebAssembly modules to minimize the risk of exploitation. Avoid using the
shrinkElements function in WebAssembly until the issue is resolved.Fix
Buffer Overflow
