RLSA-2026:64787 Moderate: xz security update

XZ Utils is an integrated collection of user-space file compression utilities based on the Lempel-Ziv-Markov chain algorithm LZMA, which performs lossless data compression. The algorithm provides a high compression ratio while keeping the decompression time short. Security Fixes: xz: XZ Utils:...

xz: XZ Utils: Denial of Service via buffer overflow in index decoding

A flaw was found in XZ Utils. When the lzmaindexdecoder function processes an empty index, and a subsequent lzmaindexappend operation is performed, insufficient memory is allocated. This can lead to a buffer overflow, potentially causing a denial of service DoS for affected systems...
