Bug ID: 51928
Summary: Security cookie in read-only section causes crash on
startup
Product: Wine
Version: unspecified
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ntdll
Assignee: wine-bugs at winehq.org
Reporter: vrbuckle at synthtools.co.uk
Distribution: ---
After some point, PE binaries are allowed to have the security cookie in a
read-only section.
set_security_cookie does not handle this and segfaults trying to write to
read-only memory.
Example binary: .NET Native compiler 2.2.x :
https://www.nuget.org/api/v2/package/runtime.win10-x64.Microsoft.Net.Native.Compiler/2.2.11-rel-30601-02
this is a zip file, the faulting binary is at tools/x64/ilc/ilc.exe
