A similar issue rose up in Windows some years back. Yes, they have dlls that do much the same as .so in _nix. But each program on Windows will first check their own folder and subfolders for a matching dll before asking the OS. And each program ship with a set of redistributable dlls from visual-c++. One of those dlls were found to have a vulnerability. And while MS could patch their office suite and related quite readily, they could at best offer a tool for scanning for vulnerable dlls in program folders and beg users to badger the software providers for updates. The sad thing right now is that various big names within the Linux community is pushing for a more Windows like distribution model, when the problem they are trying to fix is related to overly rigid package dependency trees (with the RPM package format in particular, as the primary user of the DEB format has worked around the issue with a careful package naming policy).
