"The remote AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ALSA-2023:4468 advisory.

  - Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image
    data from another site in violation of same-origin policy. This vulnerability affects Firefox < 116,
    Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4045)

  - In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This
    resulted in incorrect compilation and a potentially exploitable crash in the content process. This
    vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4046)

  - A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user
    into granting permissions. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR
    < 115.1. (CVE-2023-4047)

  - An out-of-bounds read could have led to an exploitable crash when parsing HTML with DOMParser in low
    memory situations. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR <
    115.1. (CVE-2023-4048)

  - Race conditions in reference counting code were found through code inspection. These could have resulted
    in potentially exploitable use-after-free vulnerabilities. This vulnerability affects Firefox < 116,
    Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4049)

  - In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This
    resulted in a potentially exploitable crash which could have led to a sandbox escape. This vulnerability
    affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4050)

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and
    Thunderbird 102.13. 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 < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4056)

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, and Thunderbird 115.0. 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 < 116 and Firefox ESR < 115.1.
