Date: Tue, 26 Jan 1999 21:46:06 -0700 (MST) From: Dan Burcaw <dburcaw@terraplex.com> To: linux-kernel@vger.rutgers.edu Subject: 2.2.0 SECURITY There is a bug that works only on the 2.2.0 kernel that will allow root and non-root users to crash the machine (the system reboots). To replicate this bug do following: Take any core file, and as normal user or root run: ldd core The machine will reboot, saying that it cannot get execution permissions for ./core As far as I can tell, this problem only affects x86 machines running 2.2.0. I know that PPC is not affected. Note: This problem does not occur in kernels before 2.2.0, and is apparently fixed in 2.2.0ac1. Thanks to Gennady Gurov (gurov@frii.com) for discovering this problem.
