RedHat: RHSA-2021-4231:04 Moderate: libwebp security update
Summary
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.
