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)

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3163-1 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)

  - The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any     files in that directory would be recursively deleted with the permissions of the uninstalling user     account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary     file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other     operating systems are unaffected.* This vulnerability affects Firefox < 116 and Firefox ESR < 115.1.
    (CVE-2023-4052)

  - When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code.
    *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability     affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. (CVE-2023-4054)

  - When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the     host was no longer consistent with expected cookie jar state. This could have caused requests to be sent     with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR     < 115.1. (CVE-2023-4055)

  - 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.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0450 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-3417:
    Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could     be incorrectly shown as being a document file, while in  fact it was an executable file. Newer versions of     Thunderbird will strip the character and show the correct file extension. This vulnerability affects     Thunderbird < 115.0.1 and Thunderbird < 102.13.1.

    CVE-2023-29479:
    Ribose RNP before 0.16.3 may hang when the input is malformed.

    CVE-2023-28427:
    matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 24.0.0     events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from     functioning properly, potentially impacting the consumer/'s ability to process data safely. Note that the     matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to     the consumer. This vulnerability is distinct from GHSA-rfv9-x7hh-xc32 which covers a similar issue. The     issue has been patched in matrix-js-sdk 24.0.0 and users are advised to upgrade. There are no known     workarounds for this vulnerability.

    CVE-2023-1945:
    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-2023-0547:
    OCSP revocation status of recipient certificates was not checked when sending S/Mime encrypted email, and     revoked certificates would be accepted. Thunderbird versions from 68 to 102.9.1 were affected by this bug.
    This vulnerability affects Thunderbird < 102.10.

    CVE-2023-44488:
    VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding.

    CVE-2023-32206:
    An out-of-bound read could have led to a crash in the RLBox Expat driver. This vulnerability affects     Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-32205:
    In multiple cases browser prompts could have been obscured by popups controlled by content. These could     have led to potential user confusion and spoofing attacks. This vulnerability affects Firefox < 113,     Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-32211:
    A type checking bug would have led to invalid code being compiled. This vulnerability affects Firefox <     113, Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-32207:
    A missing delay in popup notifications could have made it possible for an attacker to trick a user into     granting permissions. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird <     102.11.

    CVE-2023-32212:
    An attacker could have positioned a <code>datalist</code> element to obscure the address bar. This     vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-32213:
    When reading a file, an uninitialized value could have been used as read limit. This vulnerability affects     Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-32215:
    Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian     Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112     and Firefox ESR 102.10. 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 < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

    CVE-2023-37201:
    An attacker could have triggered a use-after-free condition when creating a WebRTC connection over HTTPS.
    This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13.

    CVE-2023-37202:
    Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to     be stored in the main compartment resulting in a use-after-free. This vulnerability affects Firefox < 115,     Firefox ESR < 102.13, and Thunderbird < 102.13.

    CVE-2023-37207:
    A website could have obscured the fullscreen notification by using a URL with a scheme handled by an     external program, such as a mailto URL. This could have led to user confusion and possible spoofing     attacks. This vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird < 102.13.

    CVE-2023-4055:
    When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the     host was no longer consistent with expected cookie jar state. This could have caused requests to be sent     with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR     < 115.1.

    CVE-2023-4574:
    When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks     could have been created at a time and eventually all simultaneously destroyed as soon as one of the     callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This     vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

    CVE-2023-4573:
    When receiving rendering data over IPC `mStream` could have been destroyed when initialized, which could     have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox <     117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

    CVE-2023-4581:

    CVE-2023-34414:
    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-2023-29539:
    When handling the filename directive in the Content-Disposition header, the filename would be truncated if     the filename contained a NULL character.
