    Sven Tantau reported about a buffer overflow vulnerability in
    chmlib. The function '_chm_decompress_block()' does not properly
    perform boundary checking, resulting in a stack-based buffer overflow.
  
Impact :

    By convincing a user to open a specially crafted ITSS or CHM file,
    using KchmViewer or a program makes use of chmlib, a remote attacker
    could execute arbitrary code with the privileges of the user running
    the software.
  
Workaround :

    There is no known workaround at this time."
