Juniper Networks released two advisories noting 13 security flaws in the Contrail Networking software-defined networking solution, with the first advisory detailing bugs in Contrail Networking versions before 2011.L4, the most severe of which are an Apache HTTP Server heap overflow, tracked as CVE-2021-26691, and two buffer overflow bugs in Pillow, tracked as CVE-2021-25289 and CVE-2021-34552.
