Summary: An update for libwebp is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. 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 Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - 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. 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 4.
