Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Improper Authorization (CVE-ID: CVE-2016-9575)

The vulnerability allows a remote authenticated user to read and manipulate data.

Ipa versions 4.2.x, 4.3.x before 4.3.3 and 4.4.x before 4.4.3 did not properly check the user's permissions while modifying certificate profiles in IdM's certprofile-mod command. An authenticated, unprivileged attacker could use this flaw to modify profiles to issue certificates with arbitrary naming or key usage information and subsequently use such certificates for other attacks.


2) Credentials management (CVE-ID: CVE-2016-7030)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

FreeIPA uses a default password policy that locks an account after 5 unsuccessful authentication attempts, which allows remote attackers to cause a denial of service by locking out the account in which system services run on.
