fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service (out-of-bounds read in strlen) by sending NFS traffic when the trace event framework is being used for nfsd. El archivo fs/nfsd/trace.h en el kernel de Linux versiones anteriores a 5.13.4, podría permitir a atacantes remotos causar una denegación de servicio (lectura fuera de los límites en strlen) mediante el envío de tráfico NFS cuando el marco de eventos de rastreo se está usando para nfsd • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.4 https://github.com/torvalds/linux/commit/7b08cf62b1239a4322427d677ea9363f0ab677c6 https://security.netapp.com/advisory/ntap-20210902-0010 • CWE-125: Out-of-bounds Read •

In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior ** EN DISPUTA ** En el archivo drivers/char/virtio_console.c en el kernel de Linux versiones anteriores a 5.13.4, la corrupción o pérdida de datos puede ser desencadenada por un dispositivo no fiable que suministre un valor buf-)len excediendo el tamaño del buffer. NOTA: El proveedor indica que la citada corrupción de datos no es una vulnerabilidad en ningún caso de uso existente; la validación de la longitud se añadió únicamente para la robustez frente a un comportamiento anómalo del sistema operativo anfitrión. • https://access.redhat.com/security/cve/cve-2021-38160 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.4 https://github.com/torvalds/linux/commit/d00d8da5869a2608e97cfede094dfc5e11462a46 https://lists.debian.org/debian-lts-announce/2021/10/msg00010.html https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html https://security.netapp.com/advisory/ntap-20210902-0010 https://www.debian.org/security/2021/dsa-4978 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2021-28169 – jetty: requests to the ConcatServlet and WelcomeFilter are able to access protected resources within the WEB-INF directory
https://notcve.org/view.php?id=CVE-2021-28169
For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to `/concat?/%2557EB-INF/web.xml` can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application. Para Eclipse Jetty versiones anteriores a 9.4.40 incluyéndola, versiones anteriores a 10.0.2 incluyéndola, versiones anteriores a 11.0.2 incluyéndola, es posible que las peticiónes al ConcatServlet con una ruta doblemente codificada acceder a recursos protegidos dentro del directorio WEB-INF. • https://github.com/eclipse/jetty.project/security/advisories/GHSA-gwcr-j4wh-j3cq https://lists.apache.org/thread.html/r04a4b4553a23aff26f42635a6ae388c3b162aab30a88d12e59d05168%40%3Cjira.kafka.apache.org%3E https://lists.apache.org/thread.html/r234f6452297065636356f43654cdacef565b8f9ceb0e0c07ffb8c73b%40%3Cdev.kafka.apache.org%3E https://lists.apache.org/thread.html/r2721aba31a8562639c4b937150897e24f78f747cdbda8641c0f659fe%40%3Cusers.kafka.apache.org%3E https://lists.apache.org/thread.html/r284de9c5399486dfff12ab9e7323ca720dd7019a9a3e11c8510a7140%40%3Cjira.kafka.apache.org%3E • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2021-22118 – spring-web: (re)creating the temporary storage directory could result in a privilege escalation within WebFlux application
https://notcve.org/view.php?id=CVE-2021-22118
In Spring Framework, versions 5.2.x prior to 5.2.15 and versions 5.3.x prior to 5.3.7, a WebFlux application is vulnerable to a privilege escalation: by (re)creating the temporary storage directory, a locally authenticated malicious user can read or modify files that have been uploaded to the WebFlux application, or overwrite arbitrary files with multipart request data. En Spring Framework, versiones 5.2.x anteriores a 5.2.15 y versiones 5.3.x anteriores a 5.3.7, una aplicación WebFlux es vulnerable a una escalada de privilegios: al (re)crear el directorio de almacenamiento temporal, un usuario malicioso autenticado localmente puede leer o modificar archivos que han sido subidos a la aplicación WebFlux, o sobrescribir archivos arbitrarios con petición de datos de múltiples partes • https://security.netapp.com/advisory/ntap-20210713-0005 https://tanzu.vmware.com/security/cve-2021-22118 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-22118 https://bugzilla.redhat.com/show_bug.cgi?id=1974854 • CWE-269: Improper Privilege Management CWE-281: Improper Preservation of Permissions CWE-668: Exposure of Resource to Wrong Sphere •
