{"id":"USN-6587-2","summary":"xorg-server vulnerabilities","details":"USN-6587-1 fixed several vulnerabilities in X.Org. This update provides\nthe corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.\n\nOriginal advisory details:\n\n Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled\n memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An\n attacker could possibly use this issue to cause the X Server to crash,\n obtain sensitive information, or execute arbitrary code. (CVE-2023-6816)\n\n Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled\n reattaching to a different master device. An attacker could use this issue\n to cause the X Server to crash, leading to a denial of service, or possibly\n execute arbitrary code. (CVE-2024-0229)\n\n Olivier Fourdan and Donn Seeley discovered that the X.Org X Server\n incorrectly labeled GLX PBuffers when used with SELinux. An attacker could\n use this issue to cause the X Server to crash, leading to a denial of\n service. (CVE-2024-0408)\n\n Olivier Fourdan discovered that the X.Org X Server incorrectly handled\n the curser code when used with SELinux. An attacker could use this issue to\n cause the X Server to crash, leading to a denial of service.\n (CVE-2024-0409)\n\n Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled\n memory when processing the XISendDeviceHierarchyEvent API. An attacker\n could possibly use this issue to cause the X Server to crash, or execute\n arbitrary code. (CVE-2024-21885)\n\n Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled\n devices being disabled. An attacker could possibly use this issue to cause\n the X Server to crash, or execute arbitrary code.
