Fedora 43 mingw-objfw Major Buffer Overflow Resolution 2026-67762cee82

fedora
Calendar Grey June 1, 2026
Dist Fedora Esm H88
Update to Fedora 43 mingw-objfw includes crucial buffer overflow fixes to enhance application security and stability.
Update to 1.5.4

Summary

ObjFW is a portable, lightweight framework for the Objective-C language. It

enables you to write an application in Objective-C that will run on any

platform supported by ObjFW without having to worry about differences between

operating systems or various frameworks you would otherwise need if you want to

be portable.

It supports all modern Objective-C features when using Clang, but is also

compatible with GCC \u2265 4.6 to allow maximum portability.

ObjFW also comes with its own lightweight and extremely fast Objective-C

runtime, which in real world use cases was found to be significantly faster

than both GNU's and Apple's runtime.

Update Information:

Update to 1.5.4. Fixes a buffer overflow caused by integer promotion rules in OFBMPImageFormatHandler and OFQOIImageFormatHandler. Update to 1.5.3
