The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-bbb8d72c6f advisory.

  • Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. Duplicate of CVE-2023-4863. (CVE-2023-5129)

  • A compromised content process could have provided malicious data in a PathRecording resulting in an out- of-bounds write, leading to a potentially exploitable crash in a privileged process. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5169)

  • During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5171)

  • Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) (CVE-2023-5217)

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