"The OS X Mavericks v10.9.5 Update is recommended for all OS X Mavericks users. It improves the stability, compatibility, and security of your Mac. This update:

• Improves the reliability of VPN connections that use USB smart cards for authentication
• Improves the reliability of accessing files located on an SMB server
• Includes Safari 7.0.6
  (Safari 7.1 (w/security fixes) is available via software update in OS X 10.9.5)

Enterprise content
For enterprise customers, this update:

• Fixes an issue with group membership in large network groups, that also might prevent administrators from performing some administrative tasks successfully.
• Allows for faster authentication when roaming on 802.1x networks which use EAP-TLS.

For detailed information about the security content of this update, see Apple security updates. (Here's the specific doc on security fixes in OS X 10.9.5)

Here's links to download pages for the delta and combo updaters:

• OS X Mavericks 10.9.5 Update (275.5 MB)
• OS X Mavericks 10.9.5 Update (Combo) (982.3 MB)

Check Apple's OS X Mavericks forum for feedback (usually on problems), although some will post in a specific mac model forum. (And here's the Safari forum as sometimes updates break 3rd party extensions or have other issues.)

BTW: I installed the delta OS X 10.9.5 update and it disabled the SSD TRIM mod I'd done for the Mac Mini's Intel 520 SSD. (Not tried the same mod (terminal commands) used with 10.9.4 yet to see if it still worked with OS X 10.9.5. I also have a backup of the patched kext from 10.9.4 I could restore (did that before finding string changes for 10.9.4), but for now just going to leave it as is.)

(Update: Nvidia released CUDA & Quadro/Geforce Driver Updates for OS X 10.9.5.)
