How to fix?

This issue was patched in ALAS-2020-1415.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-python27 package and not the libxml2-python27 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
