CVE-2019-8507

Vulnerability

CVE-2019-8507 describes multiple memory corruption issues in macOS Mojave 10.14.3 and earlier. The vulnerabilities exist in unspecified components and are triggered when processing malicious data. The exact code paths and required configurations are not disclosed in the available references [1].

Exploitation

An attacker could exploit these issues by providing malicious data to a vulnerable system, for example via a crafted file or network packet. No authentication or special privileges are mentioned as prerequisites; user interaction (e.g., opening a file or visiting a malicious site) may be required. The specific exploitation steps are not detailed in the references [1].

Impact

Successful exploitation leads to unexpected application termination, resulting in a denial of service (DoS). The description does not indicate arbitrary code execution or information disclosure, though memory corruption issues can sometimes be leveraged further [1].

Mitigation

Apple addressed these issues in macOS Mojave 10.14.4, released on March 25, 2019. Users should update to this version or later. No workarounds are documented, and the vulnerability is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog [1].
