There is no fixed version for Centos:7 libsoup.

NVD Description

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

A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.
