CVE-2021-28163 – jetty: Symlink directory exposes webapp directory contents
https://notcve.org/view.php?id=CVE-2021-28163
In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory. En Eclipse Jetty versiones 9.4.32 hasta 9.4.38, versiones 10.0.0.beta2 hasta 10.0.1 y versiones 11.0.0.beta2 hasta 11.0.1, si un usuario usa un directorio de aplicaciones web que es un enlace simbólico, el contenido del directorio de aplicaciones web se implementa como una aplicación web estática, sin darse cuenta, sirviendo las aplicaciones web en sí y cualquier otra cosa que pueda estar en ese directorio. If the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink the contents of the ${jetty.base}/webapps directory may be deployed as a static web application, exposing the content of the directory for download. The highest threat from this vulnerability is to data confidentiality. • https://github.com/eclipse/jetty.project/security/advisories/GHSA-j6qj-j888-vvgq https://lists.apache.org/thread.html/r0841b06b48324cfc81325de3c05a92e53f997185f9d71ff47734d961%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r111f1ce28b133a8090ca4f809a1bdf18a777426fc058dc3a16c39c66%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r2ea2f0541121f17e470a0184843720046c59d4bde6d42bf5ca6fad81%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r4a66bfbf62281e31bc1345ebecbfd96f35199eecd77bfe4e903e906f%40%3Cissues.ignite.apache.org%3 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2020-27223 – jetty: request containing multiple Accept headers with a large number of "quality" parameters may lead to DoS
https://notcve.org/view.php?id=CVE-2020-27223
In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of “quality” (i.e. q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values. En Eclipse Jetty versiones 9.4.6.v20170531 hasta 9.4.36.v20210114 (inclusive), versiones 10.0.0 y 11.0.0, cuando Jetty maneja una petición que contiene múltiples encabezados Accept con una gran cantidad de parámetros “quality” (es decir, q), el servidor puede entrar en un estado de denegación de servicio (DoS) debido al alto uso de CPU procesando esos valores de calidad, resultando en minutos de tiempo de CPU agotados procesando esos valores de calidad • https://github.com/motikan2010/CVE-2020-27223 https://github.com/ttestoo/Jetty-CVE-2020-27223 https://bugs.eclipse.org/bugs/show_bug.cgi?id=571128 https://github.com/eclipse/jetty.project/security/advisories/GHSA-m394-8rww-3jr7 https://lists.apache.org/thread.html/r068dfd35ce2193f6af28b74ff29ab148c2b2cacb235995576f5bea78%40%3Cissues.solr.apache.org%3E https://lists.apache.org/thread.html/r07aedcb1ece62969c406cb84c8f0e22cec7e42cdc272f3176e473320%40%3Cusers.solr.apache.org%3E https://lists.apache.org/thread.html/r0b639bd9bfaea2650221 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •
CVE-2021-21284 – privilege escalation in Moby
https://notcve.org/view.php?id=CVE-2021-21284
In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using "--userns-remap", if the root user in the remapped namespace has access to the host filesystem they can modify files under "/var/lib/docker/<remapping>" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user. En Docker versiones anteriores a 9.03.15, 20.10.3, se presenta una vulnerabilidad que involucra la opción --userns-remap en la que un acceso a una root reasignada permite una escalada de privilegios a la root actual. Cuando se usa "--userns-remap", si el usuario root en el espacio de nombres reasignado tiene acceso al sistema de archivos del host, puede modificar archivos en "/var/lib/docker/(remapping)" que causa la escritura de archivos con privilegios extendidos. • https://docs.docker.com/engine/release-notes/#20103 https://github.com/moby/moby/commit/64bd4485b3a66a597c02c95f5776395e540b2c7c https://github.com/moby/moby/releases/tag/v19.03.15 https://github.com/moby/moby/releases/tag/v20.10.3 https://github.com/moby/moby/security/advisories/GHSA-7452-xqpj-6rpc https://security.gentoo.org/glsa/202107-23 https://security.netapp.com/advisory/ntap-20210226-0005 https://www.debian.org/security/2021/dsa-4865 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

CVE-2021-3326 – glibc: Assertion failure in ISO-2022-JP-3 gconv module related to combining characters
https://notcve.org/view.php?id=CVE-2021-3326
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. La función iconv en la biblioteca GNU C (también se conoce como glibc o libc6) versiones 2.32 y anteriores, cuando procesa secuencias de entrada no válidas en la codificación ISO-2022-JP-3, se produce un fallo una aserción en la ruta del código y aborta el programa, potencialmente resultando en una denegación de servicio A flaw was found in glibc's iconv() functionality. This flaw allows an attacker capable of supplying a crafted sequence of characters to an application using iconv() to convert from ISO-2022-JP-3 to cause an assertion failure. The highest threat from this vulnerability is to system availability. • http://www.openwall.com/lists/oss-security/2021/01/28/2 https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202107-07 https://security.netapp.com/advisory/ntap-20210304-0007 https://sourceware.org/bugzilla/show_bug.cgi?id=27256 https://sourceware.org/git/?p=glibc.git%3Ba=commit%3Bh=7d88c6142c6efc160c0ee5e4f85cde382c072888 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https:/ • CWE-617: Reachable Assertion •
