| * | Remove mprotecting of struct dir_info introduced in previous commit | djm | 2008-12-30 | 1 | -9/+2 | |
| | | | | | | | | (MALLOC_OPTIONS=L). It was too slow to turn on by default, and we don't do optional security. requested by deraadt@ grumbling ok otto@ | |||||
| * | extra paranoia for malloc(3): | djm | 2008-12-29 | 1 | -2/+9 | |
| | | | | | | | | | | | | | | | | | Move all runtime options into a structure that is made read-only (via mprotect) after initialisation to protect against attacks that overwrite options to turn off malloc protections (e.g. use-after-free) Allocate the main bookkeeping data (struct dir_info) using mmap(), thereby giving it an unpredictable address. Place a PROT_NONE guard page on either side to further frustrate attacks on it. Add a new 'L' option that maps struct dir_info PROT_NONE except when in the allocator code itself. Makes attacks on it basically impossible. feedback tedu deraadt otto canacar ok otto | |||||
