motif: libXm: stack-based buffer overflow in ParseColors()

A stack-based buffer overflow in ParseColors in libXm in Common Desktop Environment 1.6 can be exploited by local low-privileged users via the dtprintinfo setuid binary to escalate their privileges to root on Solaris 10 systems. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

dtprintinfo in Common Desktop Environment 1.6 has a bug in the parser of lpstat (an invoked external command) during listing of the names of available printers. This allows low-privileged local users to inject arbitrary printer names via the $HOME/.printers file. This injection allows those users to manipulate the control flow and disclose memory contents on Solaris 10 systems. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
