• Security Update 2015-003 Yosemite (5.5MB)
• Security Update 2015-003 Yosemite (Early 2015 Macs) (5MB)

Apple's doc About Security Update 2015-003 says Security Update 2015-002 fixes are included. (The 2 items/CVE's in -003 doc were also in -002. (About 2015-002 doc revised, no longer lists 10.10.2 on those items.) No mention of today's OpenSSL update.)

I'm not running Yosemite but this update changes the OS X build number to 14C1514, and since Nvidia's graphics driver keys on the build number, an update will be required (again). I'll be checking for a download page for posting but updates may appear sooner in the Nvidia prefs panel.
   As mentioned before, if you have problems booting after the security update (nvidia drivers don't load), resetting NVRAM will clear Nvidia's prefs driver setting (revert to using default OS X drivers), as well as clearing some other settings including startup disk. (Some PC nvidia cards may not be supported by the default OS X driver however.)

Nvidia OS X 10.10.2 Graphics Driver Update:
On March 24th, Nvidia posted a download page for Graphics driver 343.02.02f04 for OS X 10.10.2 build 14C1514.
  

"This driver does not support older generation GPUs with SM1.x. Please download CUDA 6.5.45 which supports SM1.x"

Here's the download page for CUDA 6.5.45 (from Jan. 28th, 2015) and CUDA 6.0.46 update which listed OS X 10.8.x support. (I'm not able to test this but wonder if it helps users that have reported problems in the past as in this long thread on NVIDIA Card/CUDA & Adobe Premiere graphics problems.)

• Firefox 36.0.4 release notes (with security fixes)
• OpenSSL Security Advisory and v1.0.2a, 1.0.1m, 1.0.0r, 0.9.8zf Updates (openssl.org)

BTW: As first seen w/Firefox 36.0, OS X firewall still (repeatedly) reports 'Deny firefox data in from (computer's IP) port 1900 proto=17' (UPnP) with FF 36.0.4. From what I've gathered this is related to FF searching for a Roku on the local network. (I'd already disabled Firefox 'hello' video/voice chat using about:config to set loop.enabled to false (default true). That does not stop Port 1900 polling.)
