High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 60
Description
The issue is caused by an out-of-bounds read in the memory of the Firefox browser's WebSocket component. This can allow a remote attacker to disclose protected information. If WebSocket data is sent with mixed text and binary in a single message, the binary data can be corrupted, resulting in an out-of-bounds read. The read memory can be sent to the originating server in response.
Recommendations
For versions prior to 60, update to version 60 or later to resolve the issue. As a temporary workaround, consider avoiding the use of mixed text and binary data in a single WebSocket message until the issue is resolved. Restrict access to sensitive information that could be disclosed through this issue until an update can be applied.
Fix
Out of bounds Read
