Description Michael Breuer 2010-01-01 18:35:39 UTC
Description of problem:

Mingetty open_tty() allocates a 40 byte buffer for the name of the tty to open. The tty name passed on the command line is not checked for length.
Version-Release number of selected component (if applicable):

Not sure if this is a security issue as mingetty is not suid. But should still be fixed.
