firefox128, firefox128-l10n: update to 128.6.0
Security Vulnerabilities fixed in Firefox ESR 128.6
#CVE-2025-0237: WebChannel APIs susceptible to confused deputy attack
Impact: moderate
The WebChannel API, which is used to transport various information across
processes, did not check the sending principal but rather accepted the
principal being sent. This could have led to privilege escalation attacks.
#CVE-2025-0238: Use-after-free when breaking lines in text
Impact: moderate
Assuming a controlled failed memory allocation, an attacker could have
caused a use-after-free, leading to a potentially exploitable crash.
#CVE-2025-0239: Alt-Svc ALPN validation failure when redirected
Impact: moderate
When using Alt-Svc, ALPN did not properly validate certificates when the
original server is redirecting to an insecure site.
#CVE-2025-0240: Compartment mismatch when parsing JavaScript JSON module
Impact: moderate
Parsing a JavaScript module as JSON could under some circumstances cause
cross-compartment access, which may result in a use-after-free.
#CVE-2025-0241: Memory corruption when using JavaScript Text Segmentation
Impact: moderate
When segmenting specially crafted text, segmentation would corrupt memory
leading to a potentially exploitable crash.
#CVE-2025-0242: Memory safety bugs fixed in Firefox 134, Thunderbird 134,
Firefox ESR 115.19, Firefox ESR 128.6, Thunderbird 115.19, and Thunderbird
128.6
Impact: high
Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 115.18,
Firefox ESR 128.5, Thunderbird 115.18, and Thunderbird 128.5. 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-2025-0243: Memory safety bugs fixed in Firefox 134, Thunderbird 134,
Firefox ESR 128.6, and Thunderbird 128.6
Impact: moderate
Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 128.5,
and Thunderbird 128.5. 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.
