The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6703-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2024-2609, CVE-2024-2611,     CVE-2024-2614, CVE-2024-2615)

    Hubert Kario discovered that Firefox had a timing side-channel when

    performing RSA decryption. A remote attacker could possibly use this

    issue to recover sensitive information. (CVE-2023-5388)

    It was discovered that Firefox did not properly handle WASM register values in some circumstances. An     attacker could potentially exploit this issue to cause a denial of service. (CVE-2024-2606)

    Gary Kwong discovered that Firefox incorrectly updated return registers for JIT code on Armv7-A systems.
    An attacker could potentially exploit

    this issue to execute arbitrary code. (CVE-2024-2607)

    Ronald Crane discovered that Firefox did not properly manage memory during character encoding. An attacker     could potentially exploit this issue to

    cause a denial of service. (CVE-2024-2608)

    Georg Felber and Marco Squarcina discovered that Firefox incorrectly

    handled html and body tags. An attacker who was able to inject markup into

    a page otherwise protected by a Content Security Policy may have been able

    obtain sensitive information. (CVE-2024-2610)

    Ronald Crane discovered a use-after-free in Firefox when handling code in SafeRefPtr. An attacker could     potentially exploit this issue to cause a

    denial of service, or execute arbitrary code. (CVE-2024-2612)

    Max Inden discovered that Firefox incorrectly handled QUIC ACK frame

    decoding. A attacker could potentially exploit this issue to cause a

    denial of service. (CVE-2024-2613)

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:1494 advisory.

  - NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could     potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124,     Firefox ESR < 115.9, and Thunderbird < 115.9. (CVE-2023-5388)

  - An unchecked return value in TLS handshake code could have caused a potentially exploitable crash. This     vulnerability affects Firefox < 122, Firefox ESR < 115.9, and Thunderbird < 115.9. (CVE-2024-0743)

  - The encrypted subject of an email message could be incorrectly and permanently assigned to an arbitrary     other email message in Thunderbird's local cache. Consequently, when replying to the contaminated email     message, the user might accidentally leak the confidential subject to a third party. While this update     fixes the bug and avoids future message contamination, it does not automatically repair existing     contaminations. Users are advised to use the repair folder functionality, which is available from the     context menu of email folders, which will erase incorrect subject assignments. This vulnerability affects     Thunderbird < 115.8.1. (CVE-2024-1936)

  - Return registers were overwritten which could have allowed an attacker to execute arbitrary code. *Note:*     This issue only affected Armv7-A systems. Other operating systems are unaffected. This vulnerability     affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9. (CVE-2024-2607)

  - `AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding()` and `AppendEncodedCharacters()` could     have experienced integer overflows, causing underallocation of an output buffer leading to an out of     bounds write. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
    (CVE-2024-2608)

  - Using a markup injection an attacker could have stolen nonce values. This could have been used to bypass     strict content security policies. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and     Thunderbird < 115.9. (CVE-2024-2610)

  - A missing delay on when pointer lock was used could have allowed a malicious page to trick a user into     granting permissions. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird <     115.9. (CVE-2024-2611)

  - If an attacker could find a way to trigger a particular code path in `SafeRefPtr`, it could have triggered     a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 124,     Firefox ESR < 115.9, and Thunderbird < 115.9. (CVE-2024-2612)

  - Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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 < 124, Firefox ESR < 115.9, and     Thunderbird < 115.9. (CVE-2024-2614)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Return registers were overwritten which could have allowed an attacker to execute arbitrary code. *Note:*     This issue only affected Armv7-A systems. Other operating systems are unaffected. This vulnerability     affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9. (CVE-2024-2607)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0119 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2023-5388:
    It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether     high order bits of the RSA decryption result are zero. This information can be used to mount a     Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens before any     padding operations, it affects all padding modes: PKCS#1 v1.5, OAEP, and RSASVP. Both API level calls and     TLS server operation are affected.

    CVE-2024-0743:
    The Mozilla Foundation Security Advisory describes this flaw as:

    An unchecked return value in TLS handshake code could have caused a potentially exploitable crash.

    CVE-2024-2607:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Return registers were overwritten which could have allowed an attacker to execute arbitrary code.

    *Note:* This issue only affected Armv7-A systems. Other operating systems are unaffected.

    CVE-2024-2608:
    The Mozilla Foundation Security Advisory describes this flaw as:

    `AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding()` and `AppendEncodedCharacters()` could     have experienced integer overflows, causing underallocation of an output buffer leading to an out of     bounds write.

    CVE-2024-2610:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Using a markup injection an attacker could have stolen nonce values. This could have been used to bypass     strict content security policies.

    CVE-2024-2611:
    The Mozilla Foundation Security Advisory describes this flaw as:

    A missing delay on when pointer lock was used could have allowed a malicious page to trick a user into     granting permissions.

    CVE-2024-2612:
    The Mozilla Foundation Security Advisory describes this flaw as:

    If an attacker could find a way to trigger a particular code path in `SafeRefPtr`, it could have triggered     a crash or potentially be leveraged to achieve code execution.

    CVE-2024-2614:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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-2024-2616:
    The Mozilla Foundation Security Advisory describes this flaw as:

    To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead     of attempt to continue.

    CVE-2024-29944:
    The Mozilla Foundation Security Advisory describes this flaw as:

    An attacker was able to inject an event handler into a privileged object that would allow arbitrary     JavaScript execution in the parent process.
