The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2598-1 advisory.

  • A use-after-free vulnerability exists in the way certain events are processed for ImageLoader objects of Webkit WebKitGTK 2.30.4. A specially crafted web page can lead to a potential information leak and further memory corruption. In order to trigger the vulnerability, a victim must be tricked into visiting a malicious webpage. (CVE-2021-21775)

  • A use-after-free vulnerability exists in the way Webkits GraphicsContext handles certain events in WebKitGTK 2.30.4. A specially crafted web page can lead to a potential information leak and further memory corruption. A victim must be tricked into visiting a malicious web page to trigger this vulnerability.
    (CVE-2021-21779)

  • An integer overflow was addressed with improved input validation. (CVE-2021-30663)

  • A memory corruption issue was addressed with improved state management. (CVE-2021-30665)

  • A logic issue was addressed with improved state management. (CVE-2021-30689)

  • A logic issue was addressed with improved restrictions. (CVE-2021-30720)

  • Multiple memory corruption issues were addressed with improved memory handling. (CVE-2021-30734, CVE-2021-30749, CVE-2021-30799)

  • A cross-origin issue with iframe elements was addressed with improved tracking of security origins.
    (CVE-2021-30744)

  • A type confusion issue was addressed with improved state handling. (CVE-2021-30758)

  • A use after free issue was addressed with improved memory management. (CVE-2021-30795)

  • This issue was addressed with improved checks. (CVE-2021-30797)

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