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.
Security Fix(es):
* libwebp: heap-based buffer overflow in PutLE16() (CVE-2018-25011)
* libwebp: heap-based buffer overflow in WebPDecode*Into functions (CVE-2020-36328)
* libwebp: use-after-free in EmitFancyRGB() in dec/io_dec.c (CVE-2020-36329)
