1. Summary:

An update for libwebp is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from

3. Description:

The libwebp packages provide a library and tools for the WebP graphics
format. WebP is an image format with a lossy compression of digital
photographic images. WebP consists of a codec based on the VP8 format, and
a container based on the Resource Interchange File Format (RIFF).
Webmasters, web developers and browser developers can use WebP to compress,
archive, and distribute digital images more efficiently.
