The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2022:7704 advisory.

  • webkitgtk: Use-after-free leading to arbitrary code execution (CVE-2022-22624, CVE-2022-22628, CVE-2022-26709, CVE-2022-26710, CVE-2022-26717)

  • webkitgtk: Buffer overflow leading to arbitrary code execution (CVE-2022-22629)

  • webkitgtk: Cookie management issue leading to sensitive user information disclosure (CVE-2022-22662)

  • webkitgtk: Memory corruption issue leading to arbitrary code execution (CVE-2022-26700, CVE-2022-26716, CVE-2022-26719)

  • webkitgtk: Heap buffer overflow in WebCore::TextureMapperLayer::setContentsLayer leading to arbitrary code execution (CVE-2022-30293)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
