Kerentanan Stack-based Buffer Overflow pada tigervnc, x.org x server +2 lainnya. Skor CVSS 3.1 7.8 (High) menurut NVD.
A buffer overflow flaw was found 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 would copy the data regardless of the size.
