Bug 951563 (CVE-2025-1941, CVE-2025-1942, CVE-2025-1943) – <www-client/firefox{-bin,}-{128.8.0,136.0}: multiple vulnerabilities

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Christopher Fore 2025-03-18 19:21:18 UTC]

CVE-2025-1941:

Under certain circumstances, a user opt-in setting that Focus should require authentication before use could have been be bypassed (distinct from CVE-2025-0245).


CVE-2025-1942:

When String.toUpperCase() caused a string to get longer it was possible for uninitialized memory to be incorporated into the result string


CVE-2025-1943:

Memory safety bugs present in Firefox 135 and Thunderbird 135. 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.
