Description

A process isolation vulnerability in Firefox stemmed from improper
handling of javascript: URIs, which could allow content to execute in
the top-level document's process instead of the intended frame,
potentially enabling a sandbox escape, CVE-2025-4083.
A vulnerability was identified in Firefox where XPath parsing could
trigger undefined behavior due to missing null checks during attribute
access. This could lead to out-of-bounds read access and potentially,
memory corruption, CVE-2025-4087.
Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR
128.9, and Thunderbird 128.9. 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, CVE-2025-4091.
