CVE-2020-22916 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:6.
NVD Description
Note: Versions mentioned in the description apply only to the upstream xz package and not the xz package as distributed by Centos.
An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of "endless output" and "denial of service" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.
