"The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ALSA-2023:5434 advisory.

  - During the worker lifecycle, a use-after-free condition could have occured, which could have led to a
    potentially exploitable crash. This vulnerability affects Firefox < 115.0.2, Firefox ESR < 115.0.2, and
    Thunderbird < 115.0.1. (CVE-2023-3600)

  - 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)

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. Some of these bugs
    showed evidence of memory corruption and we presume that with enough effort some of these could have been
    exploited to run arbitrary code. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and
    Thunderbird < 115.3. (CVE-2023-5176)

  - 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.");
