Linux kernel 2.2 ldd core Vulnerability. CVE-1999-0400. Local exploit for linux platform

Due to a rare and subtle bug in the 2.2.0 kernel, a linux machine can be forced to reboot by an unpriviliged local user. The reason for this is because of the invalid ELF core layout and the fact that munmap wipes out a vital page table entry.

Only kernel 2.2.0 is vulnerable to this.


Take any core file,

[user@box tmp]$ ldd core

[reboot]
