Debian Security Advisory DSA-4926-1 security@debian.org

- - -------------------------------------------------------------------------
Package : lasso
CVE ID : CVE-2021-28091
It was discovered that lasso, a library which implements SAML 2.0 and
Liberty Alliance standards, did not properly verify that all assertions
in a SAML response were properly signed, allowing an attacker to
impersonate users or bypass access control.
For the stable distribution (buster), this problem has been fixed in
version 2.6.0-2+deb10u1.
We recommend that you upgrade your lasso packages.
For the detailed security status of lasso please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/lasso
