Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges escalation on systems where the X server is running with privileged access, and may...

Astra Linux – Vulnerability in xorg-server

A use-after-free flaw was discovered in the X.Org X server and Xwayland in the CreateSaverWindow function. A client can trigger a use-after-free error after changing window attributes and forcing the screen saver, resulting in information disclosure...

Astra Linux – Vulnerability in xorg-server

A use-after-free vulnerability was discovered in the ProcRenderAddGlyphs function of Xorg servers. This issue arises when the AllocateGlyph function is called to store new glyphs sent by the client to the X server. As a result, multiple entries may point to the same non-refcounted glyphs...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the handling of animated cursors by the X Rendering extension. If a client does not provide any cursors, the server assumes that at least one is present. This can lead to an out-of-bounds read and potential crash...

Astra Linux – Vulnerability in xorg-server

A flaw was discovered in xorg-x11-server in versions prior to 21.1.2 and prior to 1.20.14. An out-of-bounds access can occur in the SwapCreateRegister function. The greatest threat posed by this vulnerability is related to data confidentiality and integrity, as well as system availability...

Astra Linux – Vulnerability in xorg-server

A flaw was discovered in the 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 lead to a heap buffer overflow condition, which may result in an application...

Astra Linux – Vulnerability in xorg-server

A vulnerability, which was classified as problematic, has been identified in the X.org Server. The affected component is the function ProcXkbGetKbdByName in the file xkb/xkb.c. This vulnerability causes a memory leak. It is recommended that a patch be applied to address this issue. The identifier...

A flaw was discovered in the Big Requests extension. The length of the request is multiplied by 4 before checking against the maximum allowed size, which may lead to an integer overflow and bypassing the size check...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X server’s request handling. A non-zero value for “bytes to ignore” in a client’s request can cause the server to skip processing another client’s request, potentially leading to a denial of service...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when calculating the request length, allowing a client to bypass the length checks...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X.Org X server. This out-of-bounds read vulnerability arises from the XKB geometry processing, specifically within the CheckSetGeom and XkbAddGeomKeyAlias functions. It allows an attacker to read uninitialized or out-of-bounds memory. An attacker with access to the X1...

Astra Linux – Vulnerability in xwayland, xorg-server

A use-after-free flaw was discovered in X.Org and Xwayland. When a device is removed while it is still frozen, the events queued for that device remain active even after the device is freed. Playing back those events will lead to a use-after-free...

Astra Linux – Vulnerability in xorg-server

A out-of-bounds read flaw was discovered in the X.Org X server and Xwayland within the glXDispChangeDrawableAttributes function. A incorrect size validation check allows a client-controlled number of bytes to be read, exceeding the request buffer, resulting in information disclosure. A write path...

Astra Linux – Vulnerability in xorg-server

A flaw was discovered in the Xorg-x11-server. A out-of-bounds access issue may occur in the ProcXkbSetGeometry function due to improper validation of the request length...

Astra Linux – Vulnerability in xorg-server

A use-after-free flaw was discovered in the X.Org X server and Xwayland within the FreeCounter function. A client that sets up multiple SyncCounters and waits for those triggers can trigger a use-after-free when destroying those counters through a second client connection. This could potentially...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. If the XkbChangeTypesOfKey function is called with a value of 0 for the “groups” parameter, it will resize the key symbol table to 0, but leave the key actions unchanged. If the same function is called later with a non-zero val...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the XFIXES extension. The XFixesSetClientDisconnectMode handler does not validate the request length, allowing a client to read unintended memory from previous requests...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw occurs because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges escalation on systems where X is used...
