CVSS: 6.2EPSS: 0%CPEs: 4EXPL: 0CVE-2021-28168 – jersey: Local information disclosure via system temporary directory
https://notcve.org/view.php?id=CVE-2021-28168
Eclipse Jersey 2.28 to 2.33 and Eclipse Jersey 3.0.0 to 3.0.1 contains a local information disclosure vulnerability. This is due to the use of the File.createTempFile which creates a file inside of the system temporary directory with the permissions: -rw-r--r--. Thus the contents of this file are viewable by all other users locally on the system. As such, if the contents written is security sensitive, it can be disclosed to other local users. Eclipse Jersey versiones 2.28 hasta 2.33 y Eclipse Jersey versiones 3.0.0 hasta 3.0.1, contienen una vulnerabilidad de divulgación de información local. • https://github.com/eclipse-ee4j/jersey/pull/4712 https://github.com/eclipse-ee4j/jersey/security/advisories/GHSA-c43q-5hpj-4crv https://lists.apache.org/thread.html/r2721aba31a8562639c4b937150897e24f78f747cdbda8641c0f659fe%40%3Cusers.kafka.apache.org%3E https://lists.apache.org/thread.html/r280438f7cb4b3b1c9dfda9d7b05fa2a5cfab68618c6afee8169ecdaa%40%3Ccommits.kafka.apache.org%3E https://lists.apache.org/thread.html/r305fb82e5c005143c1e2ec986a19c0a44f42189ab2580344dc955359%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r4066176a7352e021d7a • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-378: Creation of Temporary File With Insecure Permissions CWE-379: Creation of Temporary File in Directory with Insecure Permissions CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 5.9EPSS: 0%CPEs: 38EXPL: 0CVE-2021-23841 – Null pointer deref in X509_issuer_and_serial_hash()
https://notcve.org/view.php?id=CVE-2021-23841
The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. • http://seclists.org/fulldisclosure/2021/May/67 http://seclists.org/fulldisclosure/2021/May/68 http://seclists.org/fulldisclosure/2021/May/70 https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=122a19ab48091c657f7cb1fb3af9fc07bd557bbf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=8252ee4d90f3f2004d3d0aeeed003ad49c9a7807 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://security.gentoo.org/gls • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 0CVE-2021-23840 – Integer overflow in CipherUpdate
https://notcve.org/view.php?id=CVE-2021-23840
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=6a51b9e1d0cf0bf8515f7201b68fb0a3482b3dc1 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=9b1129239f3ebb1d1c98ce9ed41d5c9476c47cb2 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https:/ • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2020-8554
Kubernetes API server in all versions allow an attacker who is able to create a ClusterIP service and set the spec.externalIPs field, to intercept traffic to that IP address. Additionally, an attacker who is able to patch the status (which is considered a privileged operation and should not typically be granted to users) of a LoadBalancer service can set the status.loadBalancer.ingress.ip to similar effect. El servidor de la API de Kubernetes en todas las versiones permite a un atacante que puede crear un servicio ClusterIP y establecer el campo spec.externalIPs, interceptar el tráfico a esa dirección IP. Adicionalmente, un atacante que sea capaz de parchear el estado (que se considera una operación privilegiada y no se debe típicamente otorgar a los usuarios) de un servicio LoadBalancer puede configurar el status.loadBalancer.ingress.ip con un efecto similar A flaw was found in kubernetes. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster. • https://github.com/jrmurray000/CVE-2020-8554 https://github.com/Dviejopomata/CVE-2020-8554 https://github.com/kubernetes/kubernetes/issues/97076 https://groups.google.com/g/kubernetes-security-announce/c/iZWsF9nbKE8 https://lists.apache.org/thread.html/r0c76b3d0be348f788cd947054141de0229af00c540564711e828fd40%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/r1975078e44d96f2a199aa90aa874b57a202eaf7f25f2fde6d1c44942%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/rcafa485d63550657f068775801aeb706b7a07140a8ebbdef82 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-283: Unverified Ownership •
CVSS: 5.9EPSS: 0%CPEs: 21EXPL: 0CVE-2020-14340 – xnio: file descriptor leak caused by growing amounts of NIO Selector file handles may lead to DoS
https://notcve.org/view.php?id=CVE-2020-14340
A vulnerability was discovered in XNIO where file descriptor leak caused by growing amounts of NIO Selector file handles between garbage collection cycles. It may allow the attacker to cause a denial of service. It affects XNIO versions 3.6.0.Beta1 through 3.8.1.Final. Se detectó una vulnerabilidad en XNIO en la que se produce un filtrado de descriptores de archivos causada por el crecimiento de la cantidad de manejadores de archivos NIO Selector entre los ciclos de recolección de basura. Puede permitir al atacante causar una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1860218 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-14340 • CWE-400: Uncontrolled Resource Consumption •
