[SECURITY] Fedora 42 Update: xz-5.8.1-2.fc42

XZ Utils are an attempt to make LZMA compression easy to use on free as in freedom operating systems. This is achieved by providing tools and libraries which are similar to use than the equivalents of the most popular existing compression algorithms. LZMA is a general purpose compression algorith...

CVE-2025-31115 XZ has a heap-use-after-free bug in threaded .xz decoder

XZ Utils provide a general-purpose data-compression library plus command-line tools. In XZ Utils 5.3.3alpha to 5.8.0, the multithreaded .xz decoder in liblzma has a bug where invalid input can at least result in a crash. The effects include heap use after free and writing to an address based on t...
