The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:1791 advisory.

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.
    (CVE-2023-1945)

  - There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode()     function and loop through to free best.bw and assign best = trial pointer. The second loop will then     return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the     AddressSanitizer will attempt a double free. (CVE-2023-1999)

  - A website could have obscured the fullscreen notification by using a combination of     <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and     <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks. This     vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <     112, and Thunderbird < 102.10. (CVE-2023-29533)

  - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly     traced. This resulted in memory corruption and a potentially exploitable crash. This vulnerability affects     Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird <     102.10. (CVE-2023-29535)

  - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-     controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash. This     vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <     112, and Thunderbird < 102.10. (CVE-2023-29536)

  - When handling the filename directive in the Content-Disposition header, the filename would be truncated if     the filename contained a NULL character. This could have led to reflected file download attacks     potentially tricking users to install malware. This vulnerability affects Firefox < 112, Focus for Android     < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29539)

  - Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be     interpreted to run attacker-controlled commands. <br>*This bug only affects Firefox for Linux on certain     Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected     Linux Distributions.*. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR <     102.10, Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29541)

  - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result. This     vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <     112, and Thunderbird < 102.10. (CVE-2023-29548)

  - Memory safety bugs present in Firefox 111 and Firefox ESR 102.9. 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 < 112, Focus for Android < 112, Firefox ESR < 102.10,     Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29550)

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

  - 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)

  - Through use of reportValidity() and window.open(), a plain-text validation message could have been     overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability     affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38497)

  - During process shutdown, a document could have caused a use-after-free of a languages service object,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,     Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38498)
