A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

 - An integer overflow was present in <code>OrderedHashTable</code> used by the JavaScript engine (CVE-2025-49710)

 - Certain canvas operations could have lead to memory corruption. (CVE-2025-49709)
