NVD Description

Note: Versions mentioned in the description apply only to the upstream xz-debuginfo package and not the xz-debuginfo package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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