Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.

jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.

In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean.

Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).

The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.1.1a (Affected 1.1.1).

Vulnerability in the Primavera Gateway component of Oracle Primavera Products Suite (subcomponent: Primavera Desktop Integration). Supported versions that are affected are 1.0, 1.1, 14.2, 15.1, 15.2, 16.1 and 16.2. Easily "exploitable" vulnerability allows high privileged attacker with network access via HTTP to compromise Primavera Gateway. While the vulnerability is in Primavera Gateway, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Primavera Gateway. CVSS 3.0 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).

Vulnerability in the Primavera Gateway component of Oracle Primavera Products Suite (subcomponent: Primavera Desktop Integration). Supported versions that are affected are 1.0, 1.1, 14.2, 15.1, 15.2, 16.1 and 16.2. Easily "exploitable" vulnerability allows high privileged attacker with network access via HTTP to compromise Primavera Gateway. While the vulnerability is in Primavera Gateway, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Primavera Gateway accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Primavera Gateway. CVSS 3.0 Base Score 8.7 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H).
