NVD9.8CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Red Hat8.6CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H

Trivy's own label is CRITICAL. Rated critical by NVD. Rated lower by Red Hat (high), AlmaLinux (high), Amazon (high), Azure Linux (high), Oracle (high), Rocky Linux (high), Ubuntu (medium).

Description

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.
