* Security fix for CVE-2010-0740OPENBSD_4_5jasper2010-03-311-3/+4
| | | | | | | | | "In TLS connections, certain incorrectly formatted records can cause an OpenSSL client or server to crash due to a read attempt at NULL." http://openssl.org/news/secadv_20100324.txt ok djm@ sthen@

| | | | | | | | | | | | --------------------------- cherrypick patch from OpenSSL 0.9.8m: *) Always check bn_wexpend() return values for failure. (CVE-2009-3245) [Martin Olsson, Neel Mehta] --------------------------- ok sthen@
* Pull Ben Lauries blind prefix injection fix for CVE-2009-3555 fromsthen2009-11-174-1/+16
| | | | | | | | | openssl 0.9.8l. As suggested by markus@, for -stable the header change is being restricted to a private file, so the minor version is not cranked here. Discussed with markus, djm, deraadt.
* MFC: fixes for OpenSSL ASN.1 invalid memory accesses (CVE-2009-0590 anddjm2009-04-083-2/+16

| | | | | | | | | | | | | | | | | | | | | | | | | | | | on sparc, it expands to something that just plain does not work, because the page size can be variable. Sorry we didn't spot this before. Backing it all out to allow sparc to build; please find a different way to fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | (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):djm2008-12-292-165/+278
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
