Security Vulnerabilities - CVEs Published In March 2017
go-jose before 1.0.4 suffers from multiple signatures exploitation. The go-jose library supports messages with multiple signatures. However, when validating a signed message the API did not indicate which signature was valid, which could potentially lead to confusion. For example, users of the library might mistakenly read protected header values from an attached signature that was different from the one originally validated.

Revive Adserver before 3.2.3 suffers from Improper Restriction of Excessive Authentication Attempts. The login page of Revive Adserver is vulnerable to password-guessing attacks. An account lockdown feature was considered, but rejected to avoid introducing service disruptions to regular users during such attacks. A random delay has instead been introduced as a countermeasure in case of password failures, along with a system to discourage parallel brute forcing. These systems will effectively allow the valid users to log in to the adserver, even while an attack is in progress.

Revive Adserver before 3.2.3 suffers from session fixation, by allowing arbitrary session identifiers to be forced and, at the same time, by not invalidating the existing session upon a successful authentication. Under some circumstances, that could have been an opportunity for an attacker to steal an authenticated session.

Revive Adserver before 3.2.3 suffers from Cross-Site Request Forgery (CSRF). The password recovery form in Revive Adserver is vulnerable to CSRF attacks. This vulnerability could be exploited to send a large number of password recovery emails to the registered users, especially in conjunction with a bug that caused recovery emails to be sent to all the users at once. Both issues have been fixed.

Such information cannot however be used directly to log in to the system, which requires a username.
