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. Security Fix(es): * libwebp: out-of-bounds read in WebPMuxCreateInternal (CVE-2018-25009) * libwebp: out-of-bounds read in ApplyFilter() (CVE-2018-25010) * libwebp: out-of-bounds read in WebPMuxCreateInternal() (CVE-2018-25012) * libwebp: out-of-bounds read in ShiftBytes() (CVE-2018-25013) * libwebp: use of uninitialized value in ReadSymbol() (CVE-2018-25014) * libwebp: out-of-bounds read in ChunkVerifyAndAssign() in mux/muxread.c (CVE-2020-36330) * libwebp: out-of-bounds read in ChunkAssignData() in mux/muxinternal.c (CVE-2020-36331) * libwebp: excessive memory allocation when reading a file (CVE-2020-36332) 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.
