DLA-2707-1 sogo -- LTS security update
- Date Reported:
- 12 Jul 2021
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2021-33054.
- More information:
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
