      <title>CVE-2023-6816 — Xorg-x11-server: heap buffer overflow in devicefocusevent and procxiquerypointer</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-6816</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat Enterprise Linux 6 Extended Lifecycle Support  - EXTENSION, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.2 Telecommunications Update Service, Red Hat Enterprise Linux 8.2 Update Services for SAP Solutions, Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions, Red Hat Enterprise Linux 8.6 Extended Update Support and 5 more&lt;/p&gt;
&lt;p&gt;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&amp;#39;s particular number of buttons, leading to a heap overflow if a bigger value was used.&lt;/p&gt;</description>

      <title>USN-6587-1 — xorg-server, xwayland vulnerabilities</title>
      <link>https://vulnerability.circl.lu/vuln/usn-6587-1</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Ubuntu:20.04:LTS: xorg-server, Ubuntu:22.04:LTS: xorg-server, Ubuntu:22.04:LTS: xwayland&lt;/p&gt;
&lt;p&gt;Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An
attacker could possibly use this issue to cause the X Server to crash,
obtain sensitive information, or execute arbitrary code. (CVE-2023-6816)&lt;/p&gt;
&lt;p&gt;Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
reattaching to a different master device. An attacker could use this issue
to cause the X Server to crash, leading to a denial of service, or possibly
execute arbitrary code. (CVE-2024-0229)&lt;/p&gt;
&lt;p&gt;Olivier Fourdan and Donn Seeley discovered that the X.Org X Server
incorrectly labeled GLX PBuffers when used with SELinux. An attacker could
use this issue to cause the X Server to crash, leading to a denial of
service. (CVE-2024-0408)&lt;/p&gt;
&lt;p&gt;Olivier Fourdan discovered that the X.Org X Server incorrectly handled
the curser code when used with SELinux. An attacker could use this issue to
cause the X Server to crash, leading to a denial of service.
(CVE-2024-0409)&lt;/p&gt;
&lt;p&gt;Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
memory when processing the XISendDeviceHierarchyEvent API. An attacker
could possibly use this issue to cause the X Server to crash, or execute
arbitrary code. (CVE-2024-21885)&lt;/p&gt;
&lt;p&gt;Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled
devices being disabled. An attacker could possibly use this issue to cause
the X Server to crash, or execute arbitrary code. (CVE-2024-21886)&lt;/p&gt;</description>
