https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239894 --- Comment #14 from Shawn Webb <shawn.webb@hardenedbsd.org> --- (In reply to Kurt Miller from comment #13) > The authors of the Stack Clash advisory indicate a 4096 byte guard region= is not difficult to jump over and avoid. Their recommendation is a 1MB gua= rd region. Restricting the value at 1 leaves this issue unaddressed. Fully agreed. However, the implementation in FreeBSD has shown to be unstab= le at values greater than 1. For extra fun, set it to a negative value. :) --=20 You are receiving this mail because: You are the assignee for the bug.=
