CVSS: 8.3EPSS: 1%CPEs: 248EXPL: 4CVE-2021-2351 – Oracle Database Weak NNE Integrity Key Derivation
https://notcve.org/view.php?id=CVE-2021-2351
Vulnerability in the Advanced Networking Option component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Advanced Networking Option. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Advanced Networking Option, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Advanced Networking Option. • http://packetstormsecurity.com/files/165255/Oracle-Database-Protection-Mechanism-Bypass.html http://packetstormsecurity.com/files/165258/Oracle-Database-Weak-NNE-Integrity-Key-Derivation.html http://seclists.org/fulldisclosure/2021/Dec/19 http://seclists.org/fulldisclosure/2021/Dec/20 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujan2023.html https://www.oracle.com/security-alerts/cpujul2021.html https:&# • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-384: Session Fixation •
CVSS: 7.5EPSS: 1%CPEs: 17EXPL: 0CVE-2021-30639 – DoS after non-blocking IO error
https://notcve.org/view.php?id=CVE-2021-30639
A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r79a7c019712b39aedf7cf4da9276d80610f04441b2a4f6506cb2daaf%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r79a7c019712b39aedf7cf4da9276d80610f04441b2a4f6506cb2daaf%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/rd84fae1f474597bdf358f5bdc0a5c453c507bd527b83e8be6b5ea3f4%40%3Cannounce.tomcat.apache.org%3E https://security.gentoo.org/glsa/202208-34 https://security.netapp.com/advisory/ntap-20210827-0007 https://www. • CWE-755: Improper Handling of Exceptional Conditions •

An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, before version 4.2.0. A specially crafted JSON file can cause a buffer overflow, resulting in multiple heap corruptions and potentially code execution. An attacker can provide a specially crafted file to trigger this vulnerability. Existe una vulnerabilidad de desbordamiento del búfer de almacenamiento dinámico explotable en la funcionalidad de persistencia de la estructura de datos de OpenCV, anterior a la versión 4.2.0. Un archivo JSON especialmente diseñado puede causar un desbordamiento del búfer, lo que da como resultado múltiples corrupciones en el montón y, potencialmente, la ejecución del código. • https://github.com/opencv/opencv/issues/15857 https://talosintelligence.com/vulnerability_reports/TALOS-2019-0853 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
