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.

An authentication bypass vulnerability was found in overt-engine. This flaw allows the creation of users in the system without authentication due to a flaw in the CreateUserSession command.

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.

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.

An Open redirect vulnerability was found in ovirt-engine versions 4.4 and earlier, where it allows remote attackers to redirect users to arbitrary web sites and attempt phishing attacks. Once the target has opened the malicious URL in their browser, the critical part of the URL is no longer visible. The highest threat from this vulnerability is on confidentiality.

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.

ovirt-engine-sdk-python before 3.4.0.7 and 3.5.0.4 does not verify that the hostname of the remote endpoint matches the Common Name (CN) or subjectAltName as specified by its x.509 certificate in a TLS/SSL session. This could allow man-in-the-middle attackers to spoof remote endpoints via an arbitrary valid certificate.

oVirt users with MANIPULATE_STORAGE_DOMAIN permissions can attach a storage domain to any data-center

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'.
