The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2024:3343 advisory.

  - A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents()     function. This issue occurs when byte-swapped length values are used in replies, potentially leading to     memory leakage and segmentation faults, particularly when triggered by a client with a different     endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory     values and then transmit them back to the client until encountering an unmapped page, resulting in a     crash. Despite the attacker's inability to control the specific memory copied into the replies, the small     length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds     reads. (CVE-2024-31080)

This issue     occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially     resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently,     ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer     is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the     system by sending a specially crafted request. (CVE-2024-31083)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0095 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-5380:
    A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and     legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if     the pointer is warped from within a window on one screen to the root window of the other screen and if the     original window is destroyed followed by another window being destroyed.

    CVE-2023-6816:
    A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for     each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the     X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap     overflow if a bigger value was used.

    CVE-2024-0229:
    An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a     device frozen by a sync grab is reattached to a different master device. This issue may lead to an     application crash, local privilege escalation (if the server runs with extended privileges), or remote     code execution in SSH X11 forwarding environments.

    CVE-2024-21885:
    A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the     allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can     trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution     in SSH X11 forwarding environments.

    CVE-2024-21886:
    A heap buffer overflow flaw was found in the DisableDevice function in the X.Org server. This issue may     lead to an application crash or, in some circumstances, remote code execution in SSH X11 forwarding     environments.

    CVE-2024-31080:
    A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents()     function.

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-2024:0652 advisory.

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

    CVE-2024-21886:
    A heap buffer overflow flaw was found in the DisableDevice function in the X.Org server. This issue may     lead to an application crash or, in some circumstances, remote code execution in SSH X11 forwarding     environments.

    CVE-2023-5380:
    A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and     legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if     the pointer is warped from within a window on one screen to the root window of the other screen and if the     original window is destroyed followed by another window being destroyed.

    An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a     device frozen by a sync grab is reattached to a different master device. This issue may lead to an     application crash, local privilege escalation (if the server runs with extended privileges), or remote     code execution in SSH X11 forwarding environments.

This can     trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution     in SSH X11 forwarding environments.

    CVE-2023-6377:
    A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to     a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or     possible remote code execution in cases where X11 forwarding is involved.

    CVE-2024-0408:
    A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the     buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a     GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the     XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.

    CVE-2024-0409:
    A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of     private at creation. It uses the cursor bits type with the cursor as private, and when initiating the     cursor, that overwrites the XSELINUX context.

    CVE-2024-31080:
    A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents()     function. This issue occurs when byte-swapped length values are used in replies, potentially leading to     memory leakage and segmentation faults, particularly when triggered by a client with a different     endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory     values and then transmit them back to the client until encountering an unmapped page, resulting in a     crash. Despite the attacker's inability to control the specific memory copied into the replies, the small     length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds     reads.

    CVE-2024-31081:
    A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIPassiveGrabDevice()     function. This issue occurs when byte-swapped length values are used in replies, potentially leading to     memory leakage and segmentation faults, particularly when triggered by a client with a different     endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory     values and then transmit them back to the client until encountering an unmapped page, resulting in a     crash. Despite the attacker's inability to control the specific memory copied into the replies, the small     length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds     reads.

    CVE-2023-5367:
    A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect     calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function     in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible     escalation of privileges or denial of service.
