The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2260 advisory.

    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)
