OpenUnix DT Library Buffer Overflow

by phiber on August 6th, 2001 A buffer overflow within some dt utilities has been discovered. When the $HOME environment variable is filled with 9000 bytes of data, dtaction, dtsession, and dtprintinfo all overflow and exit abnormally.

This overflow may result in the overwriting of stack variables, including the return address. As these programs are all setuid root, it may be possible to execute arbitrary code with the inherited privileges of root.
