==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

Summary:
Several security issues were fixed in Firefox.
Software Description:
- firefox: Mozilla Open Source web browser

checking during range analysis, leading to an out-of-bounds write
vulnerability. A attacker could use this to cause a denial of service,
or execute arbitrary code. (CVE-2024-29943)
Manfred Paul discovered that Firefox incorrectly handled MessageManager
listeners under certain circumstances. An attacker who was able to inject
an event handler into a privileged object may have been able to execute
arbitrary code. (CVE-2024-29944)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
