Ovirt-engine: potential exposure of cleartext provider passwords via web ui

A flaw was found in oVirt. A user with administrator privileges, including users with the ReadOnlyAdmin permission, may be able to use browser developer tools to view Provider passwords in cleartext.

Ovirt: authentication bypass

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.

kernel: improper initialization of the "flags" member of the new pipe_buffer

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: HTML Injection/ Reflected XSS on Windows Service Accounts homepages

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.

ovirt-engine-webadmin: does not invalidate all sessions upon logout

oVirt 3.2.2 through 3.5.0 does not invalidate the restapi session after logout from the webadmin, which allows remote authenticated users with knowledge of another user's session data to gain that user's privileges by replacing their session token with that of another user.

ovirt-engine-webadmin: session fixation

Session fixation vulnerability in the web admin interface in oVirt 3.4.0 and earlier allows remote attackers to hijack web sessions via unspecified vectors.

The python SDK before 3.1.0.6 and CLI before 3.1.0.8 for oVirt 3.1 does not check the server SSL certificate against the client keys, which allows remote attackers to spoof a server via a man-in-the-middle (MITM) attack.

ovirt-engine: non-admin user is able to access other users public SSH key

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.

ovirt-engine: Reflected cross site scripting vulnerability

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.

ovirt-engine: response_type parameter allows reflected XSS

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: account enumeration through login to web console

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.

ovirt-engine: some config files left world-writable due to improper use of os.chmod()

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'.
