Out-Of-Bounds Write

libX11.so is vulnerable to an out-of-bounds write. This is due to the length value in XGetFontPath and XListExtensions being interpreted as a signed character on different systems, which can lead to an out-of-bounds write of up to 128 bytes in front of the allocated storage...

Out-Of-Bounds Write

libX11.so is vulnerable to an out-of-bounds write. The server response consisting of a length byte followed by the actual string is not NULL-terminated, which could lead to an off-by-one override in the functions XGetFontPath, XListExtensions and XListFonts, and result in an out-of-bounds write...
