OESA-2025-1085 (CVE-2025-0237)
Vulnerability from osv_openeuler – Published: 2025-01-24 11:08 – Updated: 2026-08-06 11:08 – Source websiteMozilla Firefox is an open-source web browser, designed for standards compliance, performance and portability.
Security Fix(es):
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. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and Thunderbird < 128.6.(CVE-2025-0237)
When segmenting specially crafted text, segmentation would corrupt memory leading to a potentially exploitable crash. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Thunderbird < 134, and Thunderbird < 128.6.(CVE-2025-0241)
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. This vulnerability affects Firefox < 134, Firefox ESR < 128.6, Firefox ESR < 115.19, Thunderbird < 134, and Thunderbird < 128.6.(CVE-2025-0242)
