Debian LTS Advisory DLA-2707-1 debian-lts@lists.debian.org
https://www.debian.org/lts/security/ Anton Gladky
July 12, 2021 https://wiki.debian.org/LTS
- - -------------------------------------------------------------------------
Package : sogo
Version : 3.2.6-2+deb9u1
CVE ID : CVE-2021-33054
One security issue has been discovered in sogo.
SOGo does not validate the signatures of any SAML assertions it receives.
Any actor with network access to the deployment could impersonate users when
SAML is the authentication method.
For Debian 9 stretch, this problem has been fixed in version
3.2.6-2+deb9u1.
We recommend that you upgrade your sogo packages.
ATTENTION! If you are using SAML authentication, use sogo-tool to immediately
delete users sessions and force all users to visit the login page:
sogo-tool -v expire-sessions 1
systemctl restart memcached
For the detailed security status of sogo please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/sogo
