Medium
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Firefox versions prior to 125
Description:
The issue is related to the JIT component of the Mozilla Firefox browser, which incorrectly optimizes MSubstr operations, leading to out-of-bounds reads. This can allow a remote attacker to disclose protected information.
Recommendations:
For versions prior to 125, update to version 125 or later to resolve the issue. As a temporary workaround, consider disabling the JIT compiler until a patch is available. Restrict access to sensitive information to minimize the risk of exploitation.
