After installing KB5005076 on Windows Server 2012 R2, IIS application pools which are set to allow 32 bit mode begin to crash, writing BEX errors (Buffer Overflow Exception) to the event log, referencing either w3wp or regsvr32 as the faulting process.Uninstalling this KB/security patch (or running all IIS pools in 64 bit mode) will fix the issue. As to why this is an issue I am unsure at this time, but wanted to share this in case others are having this issue as there didn't seem to be any information out there about this possible link yet.Faulting application name: w3wp.exe, version: 8.5.g6W.16384, time stamp:Faulting module name: ntdll.dll, version: 6.3.g6W.2cogo, time stamp: Dx60eg12D8Exception code: DxcCCNN5Fault offset: DxC02a8cOFaulting process id: Dx24e4Faulting application start time: MI d7a3e4d12ae73aFaulting application path:Faulting module path:Report ld: 178c8755-Cfd8-11 ec-812e-C05056%3c8fFaulting package full name:Faulting package-relative application ID:I will update this as more information comes to light.
