Summary
xz security update
Details

XZ Utils is free general-purpose data compression software with a high compression ratio. XZ Utils were written for POSIX-like systems, but also work on some not-so-POSIX systems. XZ Utils are the successor to LZMA Utils.

Security Fix(es):

XZ Utils provide a general-purpose data-compression library plus command-line tools. Prior to version 5.8.3, if lzmaindexdecoder() was used to decode an Index that contained no Records, the resulting lzmaindex was left in a state where where a subsequent lzmaindex_append() would allocate too little memory, and a buffer overflow would occur. This issue has been patched in version 5.8.3.(CVE-2026-34743)
