https://notcve.org/view.php?id=CVE-2020-28196
MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit. MIT Kerberos versión 5 (también se conoce como krb5) versiones anteriores a 1.17.2 y versiones 1.18.x anteriores a 1.18.3, permite una recursividad ilimitada por medio de un mensaje Kerberos codificado en ASN.1 porque el soporte de la biblioteca lib/krb5 /asn.1/asn1_encode.c para longitudes indefinidas BER carece un límite de recursividad A flaw was found in krb5. MIT Kerberos 5 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit. • https://github.com/krb5/krb5/commit/57415dda6cf04e73ffc3723be518eddfae599bfd https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/11/msg00011.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/45KKOZQWIIIW5C45PJVGQ32AXBSYNBE7 https://lists.fedoraproject.org/archives • CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2020-27216
In Eclipse Jetty versions 1.0 thru 9.4.32.v20200930, 10.0.0.alpha1 thru 10.0.0.beta2, and 11.0.0.alpha1 thru 11.0.0.beta2O, on Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability. En Eclipse Jetty versiones 1.0 hasta 9.4.32.v20200930, versiones 10.0.0.alpha1 hasta 10.0.0.beta2 y versiones 11.0.0.alpha1 hasta 11.0.0.beta2O, en sistemas similares a Unix, el directorio temporal del sistema es compartido entre todos los usuarios en ese sistema. • https://bugs.eclipse.org/bugs/show_bug.cgi?id=567921 https://github.com/eclipse/jetty.project/security/advisories/GHSA-g3wg-6mcf-8jj6#advisory-comment-63053 https://lists.apache.org/thread.html/r0259b14ae69b87821e27fed1f5333ea86018294fd31aab16b1fac84e%40%3Cissues.beam.apache.org%3E https://lists.apache.org/thread.html/r07525dc424ed69b3919618599e762f9ac03791490ca9d724f2241442%40%3Cdev.felix.apache.org%3E https://lists.apache.org/thread.html/r09b345099b4f88d2bed7f195a96145849243fb4e53661aa3bcf4c176%40%3Cissues.zookeeper.apache.org%3E https://lists.apache. • CWE-377: Insecure Temporary File CWE-378: Creation of Temporary File With Insecure Permissions CWE-379: Creation of Temporary File in Directory with Insecure Permissions •
