A heap-based buffer over-read vulnerability was found in the X.org server's ProcAppleDRICreatePixmap() 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.

The remote host is affected by the vulnerability described in GLSA-202411-08 (X.Org X server, XWayland: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in X.Org X server and XWayland. Please review the CVE     identifiers referenced below for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

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

According to the versions of the xorg-x11-server package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. 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)

According to the versions of the xorg-x11-server package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation.
    If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a     dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free     later.(CVE-2023-1393)

    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.(CVE-2023-5367)

    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-2023-5380)

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-2024-31082)

  - A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. 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)

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

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6721-1 advisory.

    It was discovered that X.Org X Server incorrectly handled certain data. An attacker could possibly use     this issue to expose sensitive information. (CVE-2024-31080, CVE-2024-31081, CVE-2024-31082)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The version of xorg-server installed on the remote host is prior to 1.20.14 / 21.1.12 / 21.1.4 / 23.2.5. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-094-01 advisory.

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