CVSS: 5.9EPSS: 96%CPEs: 213EXPL: 7CVE-2021-45105 – Apache Log4j2 does not always protect from infinite recursion in lookup evaluation
https://notcve.org/view.php?id=CVE-2021-45105
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. Apache Log4j2 versiones 2.0-alpha1 hasta 2.16.0 (excluyendo las versiones 2.12.3 y 2.3.1) no protegían de la recursión no controlada de las búsquedas autorreferenciales. Esto permite a un atacante con control sobre los datos de Thread Context Map causar una denegación de servicio cuando es interpretada una cadena diseñada. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45105 https://github.com/pravin-pp/log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105-1 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-dileepdkumar-https-github.com-pravin-pp-log4j2-CVE-2021-45105-v htt • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
CVSS: 7.5EPSS: 2%CPEs: 37EXPL: 0CVE-2021-42340 – DoS via memory leak with WebSocket connections
https://notcve.org/view.php?id=CVE-2021-42340
The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. La corrección del bug 63362 presente en Apache Tomcat versiones 10.1.0-M1 hasta 10.1.0-M5, versiones 10.0.0-M1 hasta 10.0.11, versiones 9.0.40 hasta 9.0.53 y versiones 8.5.60 hasta 8.5.71, introducía una pérdida de memoria. El objeto introducido para recopilar métricas para las conexiones de actualización HTTP no se liberaba para las conexiones WebSocket una vez que se cerraba la conexión. • https://kc.mcafee.com/corporate/index?page=content&id=SB10379 https://lists.apache.org/thread.html/r8097a2d1550aa78e585fc77e602b9046e6d4099d8d132497c5387784%40%3Ccommits.myfaces.apache.org%3E https://lists.apache.org/thread.html/r83a35be60f06aca2065f188ee542b9099695d57ced2e70e0885f905c%40%3Cannounce.tomcat.apache.org%3E https://security.gentoo.org/glsa/202208-34 https://security.netapp.com/advisory/ntap-20211104-0001 https://www.debian.org/security/2021/dsa-5009 https://www.oracle.com/security-alerts/cpuapr2022.html https://www • CWE-772: Missing Release of Resource after Effective Lifetime •

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 •

When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected.
