    The X.Org project reports:

                libXpm uses a number of internal helper functions to parse the XPM                 file format.
                One of these internal functions, xpmNextString(), checks for the                 NULL terminator when looking for the end of the current string but                 not when looking for the beginning of the next string.
                A small XPM file with a malformed color table definition may cause                 the function xpmNextWord(), called from xpmParseColors() following                 a call to xpmNextString(), to start past the actual end of the file,                 causing an out-of-bound read.
