Bug#538432: LOWRAM mmap: Invalid argument - segfault on start-up

2009-08-14 Thread Matthieu CASTET
Package: dosemu
Version: 1.4.0+svn.1828-3
Severity: normal

Hi,

this may be because process can't map anymore page at offset 0 for
security reason (check all recent exploit about NULL pointer in
the kernel).
Running dosemu as root work (using selinx should also work).

Note that when dosemu detect 'LOWRAM mmap' failure, it should end
by a SIGSEGV.
