Synopsis: Moderate: libwebp security update Advisory ID: RHSA-2021:4231-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:4231 Issue date: 2021-11-09 CVE Names: CVE-2018-25009 CVE-2018-25010 CVE-2018-25012 CVE-2018-25013 CVE-2018-25014 CVE-2020-36330 CVE-2020-36331 CVE-2020-36332 =====================================================================
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 the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64
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.
