"The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0029 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

      CVE-2023-25737:
      An invalid downcast from nsTextNode to SVGElement could have lead to undefined behavior.

      CVE-2023-25735:
      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 after unwrapping the proxy.

      CVE-2023-25729:
      Permission prompts for opening external schemes were only shown for ContentPrincipals resulting in
    extensions being able to open them without user interaction via ExpandedPrincipals. This could lead to
    further malicious actions such as downloading files or interacting with software already installed on the
    system.

      CVE-2023-0767:
      An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory
    writes via PKCS 12 Safe Bag attributes being mishandled.

      CVE-2023-0616:
      If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts
    to process and display the message, which could cause Thunderbird's user interface to lock up and no
    longer respond to the user's actions. An attacker could send a crafted message with this structure to
    attempt a DoS attack.

      CVE-2023-25739:
      Module load requests that failed were not being checked as to whether or not they were cancelled causing
    a use-after-free in ScriptLoadContext.

      CVE-2023-0430:
      Certificate OCSP revocation status was not checked when verifying S/Mime signatures. Mail signed with a
    revoked certificate would be displayed as having a valid signature. Thunderbird versions from 68 to
    102.7.0 were affected by this bug.

      CVE-2023-25732:
      When encoding data from an inputStream in xpcom the size of the input being encoded was not correctly
    calculated potentially leading to an out of bounds memory write.

      CVE-2023-25742:
      When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the
    tab to crash.

      CVE-2023-25743:
      A lack of in app notification for entering fullscreen mode could have lead to a malicious website
    spoofing browser chrome.

      CVE-2023-25744:
      Mozilla developers Kershaw Chang and the Mozilla Fuzzing Team reported memory safety bugs present in
    Firefox 109 and Firefox ESR 102.7. 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-2023-25746:
      Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in Firefox ESR 102.7.
    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-2023-25728:
      The Content-Security-Policy-Report-Only header could allow an attacker to leak a child iframe's
    unredacted URI when interaction with that iframe triggers a redirect.

      CVE-2023-25730:
      A background script invoking requestFullscreen and then blocking the main thread could force the browser
    into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks.
