High
| Vector | AV:N/AC:L/Au:N/C:N/I:C/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 118
Description
The issue is related to an integer overflow in the Alternate Services component of the Firefox web browser. This could lead to an out-of-bounds write to privileged process memory, potentially allowing a remote attacker to compromise data integrity. The vulnerability is specifically related to non-standard configurations where a preference allowing non-HTTPS Alternate Services (
network.http.altsvc.oe) is enabled.Recommendations
For Firefox versions prior to 118, update to version 118 or later to resolve the issue.
As a temporary workaround, consider disabling the non-standard preference allowing non-HTTPS Alternate Services (
network.http.altsvc.oe) until a patch is applied.Fix
