Description Guilherme de Almeida Suckevicz 2023-01-11 14:12:59 UTC 
When reading XPM images from a file with libXpm 3.5.14 or older, if a comment in the file is not closed (i.e. a C-style comment starts with "/*" and is missing the closing "*/"), the ParseComment() function will loop forever calling getc() to try to read the rest of the comment, failing to notice that it has returned EOF, which may cause a denial of service to the calling program.
