Ubuntu 12.10 / 13.04 : keystone vulnerabilities (USN-1875-1)

medium Nessus Plugin ID 66893

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Eoghan Glynn and Alex Meade discovered that Keystone did not properly perform expiry checks for the PKI tokens used in Keystone. If Keystone were setup to use PKI tokens, a previously authenticated user could continue to use a PKI token for longer than intended. This issue only affected Ubuntu 12.10 which does not use PKI tokens by default.
(CVE-2013-2104)

Jose Castro Leon discovered that Keystone did not properly authenticate users when using the LDAP backend. An attacker could obtain valid tokens and impersonate other users by supplying an empty password. By default, Ubuntu does not use the LDAP backend.
(CVE-2013-2157).

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.

Solution

Update the affected python-keystone package.
