Astra Linux – Vulnerability in xorg-server

A stack-based buffer overflow vulnerability was discovered in the X.Org X server and Xwayland. The X server has multiple stack buffers with a size of XkbMaxShiftLevel XkbNumKbdGroups, but the CheckKeyTypes function does not verify or limit non-canonical key types to XkbMaxShiftLevel. A client can...

Astra Linux – Vulnerability in xorg-server

A stack-based buffer overflow vulnerability was discovered in the X.Org X server and Xwayland. The XkbSetMapChecks function declares a fixed-size stack buffer, mapWidths256, indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a position controlled by the client,...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in the GnuTLS library, specifically in the gnutlspkcs11tokeninit function, which handles PKCS11 token initialization. When a token label longer than expected is processed, the function writes beyond the end of a fixed-size stack buffer. This programming error can cause...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...
