CVE-2024-2614Network attack vector

Arbitrary code execution via memory corruption

Published Mar 19, 2024 · Updated Feb 13, 2025

Memory corruption in Mozilla Firefox before 124, Firefox ESR before 115.9, and Thunderbird before 115.9 allows attackers to run arbitrary code. The four underlying memory-safety defects show evidence of memory corruption, but Mozilla has not disclosed their affected code loci or unsafe operations. Trigger details are not public; in Thunderbird, email messages cannot generally reach these flaws because scripting is disabled while mail is read, limiting exposure to browser-like contexts.
