Medium Nessus Plugin ID 102777


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that PySAML2 incorrectly handled certain SAML XML requests and responses. A remote attacker could use this issue to read arbitrary files.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected python-pysaml2 and / or python3-pysaml2 packages.
