Description Guilherme de Almeida Suckevicz 2021-08-24 14:17:57 UTC

In GNOME grilo though 0.3.13, grl-net-wc.c does not enable TLS certificate verification on the SoupSessionAsync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

Comment 1 Guilherme de Almeida Suckevicz 2021-08-24 14:18:12 UTC

Created grilo tracking bugs for this issue:

Affects: fedora-all [bug 1997162]

Comment 2 Bastien Nocera 2021-08-24 15:35:41 UTC

Fedora 33 update:
https://bodhi.fedoraproject.org/updates/FEDORA-2021-301dfb76b3

That was the last supported version of Fedora to be potentially vulnerable.

Comment 3 Garrett Tucker 2021-08-24 16:53:59 UTC

RHEL 9 is not affected as the patch listed above has been applied. However, RHEL 8.5.0 and below is affected by this and should have the patch applied but is delegated to the engineering teams.
