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

    CVE-2024-1553:
    Memory safety bugs present in Firefox 122, Firefox ESR 115.7, and Thunderbird 115.7. 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. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and
    Thunderbird < 115.8.

    CVE-2024-1552:
    Incorrect code generation could have led to unexpected numeric conversions and potential undefined
    behavior.*Note:* This issue only affects 32-bit ARM devices. This vulnerability affects Firefox < 123,
    Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2024-1551:
    Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker
    could control the Content-Type response header, as well as control part of the response body, they could
    inject Set-Cookie response headers that would have been honored by the browser. This vulnerability affects
    Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2024-1550:
    A malicious website could have used a combination of exiting fullscreen mode and `requestPointerLock` to
    cause the user's mouse to be re-positioned unexpectedly, which could have led to user confusion and
    inadvertently granting permissions they did not intend to grant. This vulnerability affects Firefox < 123,
    Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2024-1548:
    A website could have obscured the fullscreen notification by using a dropdown select input element. This
    could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 123,
    Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2024-1547:
    Through a series of API calls and redirects, an attacker-controlled alert dialog could have been displayed
    on another website (with the victim website's URL shown). This vulnerability affects Firefox < 123,
    Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2024-0755:
    Memory safety bugs present in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6. 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 < 122, Firefox ESR < 115.7, and
    Thunderbird < 115.7.

    CVE-2024-0753:
    In specific HSTS configurations an attacker could have bypassed HSTS on a subdomain. This vulnerability
    affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.

    CVE-2024-0751:
    A malicious devtools extension could have been used to escalate privileges. This vulnerability affects
    Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.

    CVE-2024-0750:
    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 < 122, Firefox ESR < 115.7, and Thunderbird
    < 115.7.

    CVE-2024-0749:
    A phishing site could have repurposed an `about:` dialog to show phishing content with an incorrect origin
    in the address bar. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird <
    115.7.

    CVE-2024-0747:
    When a parent page loaded a child in an iframe with `unsafe-inline`, the parent Content Security Policy
    could have overridden the child Content Security Policy. This vulnerability affects Firefox < 122, Firefox
    ESR < 115.7, and Thunderbird < 115.7.

    CVE-2024-0746:
    A Linux user opening the print preview dialog could have caused the browser to crash. This vulnerability
    affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.

    CVE-2024-0742:
    It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by
    the user due to an incorrect timestamp used to prevent input after page load. This vulnerability affects
    Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.

    CVE-2024-0741:
    An out of bounds write in ANGLE could have allowed an attacker to corrupt memory leading to a potentially
    exploitable crash. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.

    CVE-2023-6867:
    The timing of a button click causing a popup to disappear was approximately the same length as the anti-
    clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring
    them to click where the permission grant button would be about to appear. This vulnerability affects
    Firefox ESR < 115.6 and Firefox < 121.

    CVE-2023-6865:
    `EncryptingOutputStream` was susceptible to exposing uninitialized data.  This issue could only be abused
    in order to write data to a local disk which may have implications for private browsing mode. This
    vulnerability affects Firefox ESR < 115.6 and Firefox < 121.

    CVE-2023-6864:
    Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 < 115.6, Thunderbird < 115.6, and
    Firefox < 121.

    CVE-2023-6863:
    The `ShutdownObserver()` was susceptible to potentially undefined behavior due to its reliance on a
    dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR < 115.6, Thunderbird
    < 115.6, and Firefox < 121.

    CVE-2023-6862:
    A use-after-free was identified in the `nsDNSService::Init`.  This issue appears to manifest rarely during
    start-up. This vulnerability affects Firefox ESR < 115.6 and Thunderbird < 115.6.

    CVE-2023-6861:
    The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless
    mode. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

    CVE-2023-6860:
    The `VideoBridge` allowed any content process to use textures produced by remote decoders.  This could be
    abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and
    Firefox < 121.

    CVE-2023-6859:
    A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability
    affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

    CVE-2023-6858:
    Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling.
    This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

    CVE-2023-6857:
    When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller
    than necessary.
    *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is
    unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

    CVE-2023-6856:
    The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems
    with the Mesa VM driver.  This issue could allow an attacker to perform remote code execution and sandbox
    escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

    CVE-2023-6212:
    Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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 < 120, Firefox ESR < 115.5.0, and
    Thunderbird < 115.5.

    CVE-2023-6209:
    Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal /../ part in the
    path could be used to override the specified host. This could contribute to security problems in web
    sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

    CVE-2023-6208:
    When using X11, text selected by the page using the Selection API was erroneously copied into the primary
    selection, a temporary storage not unlike the clipboard.
    *This bug only affects Firefox on X11. Other systems are unaffected.* This vulnerability affects Firefox <
    120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

    CVE-2023-6207:
    Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox
    < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

    CVE-2023-6206:
    The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on
    permission prompts. It was possible to use this fact to surprise users by luring them to click where the
    permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR <
    115.5.0, and Thunderbird < 115.5.

    CVE-2023-6205:
    It was possible to cause the use of a MessagePort after it had already been freed, which could potentially
    have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and
    Thunderbird < 115.5.

    CVE-2023-6204:
    On some systemsdepending on the graphics settings and driversit was possible to force an out-of-
    bounds read and leak memory data into the images created on the canvas element. This vulnerability affects
    Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

    CVE-2024-1546:
    When storing and re-accessing data on a networking channel, the length of buffers may have been confused,
    resulting in an out-of-bounds memory read. This vulnerability affects Firefox < 123, Firefox ESR < 115.8,
    and Thunderbird < 115.8.

    CVE-2024-1549:
    If a website set a large custom cursor, portions of the cursor could have overlapped with the permission
    dialog, potentially resulting in user confusion and unexpected granted permissions. This vulnerability
    affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.

    CVE-2023-52425:
    libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are
    required in the case of a large token for which multiple buffer fills are needed.
