CVE-2022-42927

A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of a same-origin policy violation that could have allowed the theft of cross-origin URL entries, leaking the result of a redirect via `performance.getEntries()`.

7.5 (High)
CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
CWE-829 - Inclusion of Functionality from Untrusted Control Sphere

CVE-2022-42928

A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of certain types of allocations that were missing annotations that, if the Garbage Collector was in a specific state, could lead to memory corruption and a potentially exploitable crash.

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVE-2022-42929

A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of a website called `window.print()` causing a denial of service of the browser, which may persist beyond browser restart depending on the user's session restore settings.

6.1 (Medium)
CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
CWE-400 - Uncontrolled Resource Consumption
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the update, Firefox must be restarted for the changes to take effect. https://access.redhat.com/errata/RHSA-2022:7071
CVE-2022-42932

The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers Ashley Hale and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 105 and Firefox ESR 102.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
