The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:3590 advisory.

  - The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to     protect prompts and permission dialogs from attacks that exploit human response time delays. If a     malicious page elicited user clicks in precise locations immediately before navigating to a site with a     certificate error and made the renderer extremely busy at the same time, it could create a gap between     when the error page was loaded and when the display actually refreshed. With the right timing the elicited     clicks could land in that gap and activate the button that overrides the certificate error for that site.
    This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12. (CVE-2023-34414)

  - Memory safety bugs present in Firefox 113, Firefox ESR 102.11, and Thunderbird 102.12. 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 ESR < 102.12, Firefox < 114, and     Thunderbird < 102.12. (CVE-2023-34416)

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 102.12. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-21 advisory.

  - Mozilla developers and community members Gabriele Svelto, Andrew McCreight, the Mozilla Fuzzing Team, Sean     Feng, and Sebastian Hengst reported memory safety bugs present in Thunderbird 102.11. 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. (CVE-2023-34416)

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 114.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-20 advisory.

  - Mozilla developers and community members Andrew McCreight, Randell Jesup, and the Mozilla Fuzzing Team     reported memory safety bugs present in Firefox 113. 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. (CVE-2023-34417)

    (CVE-2023-34414)

  - When choosing a site-isolated process for a document loaded from a data: URL that was the result of a     redirect, Firefox would load that document in the same process as the site that issued the redirect. This     bypassed the site-isolation protections against Spectre-like attacks on sites that host an open     redirect. Firefox no longer follows HTTP redirects to data: URLs. (CVE-2023-34415)

  - Mozilla developers and community members Gabriele Svelto, Andrew McCreight, the Mozilla Fuzzing Team, Sean     Feng, and Sebastian Hengst reported memory safety bugs present in Firefox 113 and Firefox ESR 102.11. 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. (CVE-2023-34416)

The remote NewStart CGSL host, running version MAIN 6.02, has firefox packages installed that are affected by multiple vulnerabilities:

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This     vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2021-4140)

  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in     Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in     the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks     are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a     logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are     affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

  - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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 ESR < 78.14, Thunderbird < 78.14,     and Firefox < 92. (CVE-2021-38493)

  - During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)
