NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-devel package and not the libsoup-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.
