The Single Sign On Client (ubuntu-sso-client) for Ubuntu 11.04 and 11.10 does not properly validate SSL certificates when using HTTPS, which allows remote attackers to spoof a server and modify or read sensitive data via a man-in-the-middle (MITM) attack.

Security readout for executives and security teams

This flaw affected Ubuntu's Single Sign On Client on Ubuntu 11.04 and 11.10. It could fail to properly validate SSL certificates, letting a network-positioned attacker impersonate a server and read or alter sensitive data in transit. Exposure is likely limited to legacy Ubuntu 11.04 or 11.10 systems using ubuntu-sso-client. These releases are old, so current exposure depends on whether obsolete endpoints, images, or archived systems remain in use. Treat this as a legacy exposure issue. It is urgent only if old Ubuntu 11.04 or 11.10 systems still handle credentials or sensitive data over networks where interception is plausible. Mitigation focus: Check Ubuntu USN-1464-1 for vendor update guidance and fixed package details.; Inventory Ubuntu 11.04 and 11.10 systems for ubuntu-sso-client usage.; Update or remove affected ubuntu-sso-client installations according to Ubuntu guidance..
