oVirt Ovirt-engine

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

ovirt-engine 3.2 running on Linux kernel 3.1 and newer creates certain files world-writeable due to an upstream kernel change which impacted how python's os.chmod() works when passed a mode of '-1'.

Ovirt: authentication bypass

A flaw was found in ovirt-engine 4.4.3 and earlier allowing an authenticated user to read other users' personal information, including name, email and public SSH key.

A flaw was found in Ovirt Engine's web interface in ovirt 4.4 and earlier, where it did not filter user-controllable parameters completely, resulting in a reflected cross-site scripting attack. This flaw allows an attacker to leverage a phishing attack, steal an unsuspecting user's cookies or other confidential information, or impersonate them within the application's context.

A cross-site scripting vulnerability was reported in the oVirt-engine's OAuth authorization endpoint before version 4.3.8. URL parameters were included in the HTML response without escaping. This flaw would allow an attacker to craft malicious HTML pages that can run scripts in the context of the user's oVirt session.

An HTML injection/reflected Cross-site scripting (XSS) vulnerability was found in the ovirt-engine. A parameter "error_description" fails to sanitize the entry, allowing the vulnerability to trigger on the Windows Service Accounts home pages.

The web console login form in ovirt-engine before version 4.2.3 returned different errors for non-existent users and invalid passwords, allowing an attacker to discover the names of valid user accounts.
