Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
The python-pillow packages contain a Python image processing library that provides extensive file format support, an efficient internal representation, and powerful image-processing capabilities.
Security Fix(es) :
python-pillow: improperly restricted operations on memory buffer in libImaging/PcxDecode.c (CVE-2020-5312)
python-pillow: reading specially crafted image files leads to allocation of large amounts of memory and denial of service (CVE-2019-16865)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
