We’ve shortened some of the lines slightly to make them easier to read, but the variety of bugs fixed in this round of patches is clear:Īpps may cause a system crash or write to kernel memoryĪpps may execute arbitrary code with kernel privilegesĪttackers in a privileged network position may intercept Bluetooth trafficįiles may be incorrectly rendered to execute JavaScript Nevertheless, where there’s a memory mismanagement flaw that can be triggered by remotely-supplied content, it’s wise to assume that if exploitation is possible on one platform, it can probably be figured out for other platforms, too.įor each patched bug, Apple lists its possible impact, so we filtered all the Impact: lines out of the 11 different advisories to give you an idea of the range of different issues fixed, which came to 41 in all. This is a reminder that vulnerabilities in cross-platform programming libraries may require vendors to put out updates for all the platforms on which that library is used.īugs such as buffer overflows and use-after-free errors can’t always be exploited on every platform, and even if they can, each variant of the exploit might need a lengthy phase of experimentation all of its own.

Note that DLL loading errors generally don’t allow attackers to perform what’s called remote code execution (RCE), but merely to trick you into using a legitimate program to load up an untrusted component that’s has already been downloaded locally onto your computer.
The bug fixed in Windows Migration Assistant seems to be a DLL loading flaw that affects the Windows version of the software – an app that might, ironically, be the last Windows program you ever need to run.
