Security Vulnerabilities - CVEs Published In March 2019
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored. It is a requirement of using this cipher that nonce values are unique. Messages encrypted using a reused nonce value are susceptible to serious confidentiality and integrity attacks. If an application changes the default nonce length to be longer than 12 bytes and then makes a change to the leading bytes of the nonce expecting the new value to be a new unique nonce then such an application could inadvertently encrypt messages with a reused nonce. Additionally the ignored bytes in a long nonce are not covered by the integrity guarantee of this cipher. Any application that relies on the integrity of these ignored leading bytes of a long nonce may be further affected. Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe because no such use sets such a long nonce value. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. OpenSSL versions 1.1.1 and 1.1.0 are affected by this issue. Due to the limited scope of affected deployments this has been assessed as low severity and therefore we are not creating new releases at this time. Fixed in OpenSSL 1.1.1c (Affected 1.1.1-1.1.1b). Fixed in OpenSSL 1.1.0k (Affected 1.1.0-1.1.0j).

A vulnerability in the controller authorization functionality of Cisco Nexus 9000 Series ACI Mode Switch Software could allow an authenticated, local attacker to escalate standard users with root privilege on an affected device. The vulnerability is due to a misconfiguration of certain sudoers files for the bashroot component on an affected device. An attacker could exploit this vulnerability by authenticating to the affected device with a crafted user ID, which may allow temporary administrative access to escalate privileges. A successful exploit could allow the attacker to escalate privileges on an affected device. This Vulnerability has been fixed in version 4.0(1h)

A vulnerability in the Cisco Nexus 9000 Series Fabric Switches running in Application-Centric Infrastructure (ACI) mode could allow an authenticated, local attacker to read arbitrary files on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms of user-supplied input sent to an affected device. A successful exploit could allow the attacker unauthorized access to read arbitrary files on an affected device. This vulnerability has been fixed in version 14.0(1h).

A Denial of Service vulnerability was found in Apache Qpid Broker-J versions 6.0.0-7.0.6 (inclusive) and 7.1.0 which allows an unauthenticated attacker to crash the broker instance by sending specially crafted commands using AMQP protocol versions below 1.0 (AMQP 0-8, 0-9, 0-91 and 0-10). Users of Apache Qpid Broker-J versions 6.0.0-7.0.6 (inclusive) and 7.1.0 utilizing AMQP protocols 0-8, 0-9, 0-91, 0-10 must upgrade to Qpid Broker-J versions 7.0.7 or 7.1.1 or later.
