Summary
Moderate: libwebp security update
Details

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.
