CVSS: 7.5EPSS: 1%CPEs: 3EXPL: 0CVE-2021-46828 – libtirpc: DoS vulnerability with lots of connections
https://notcve.org/view.php?id=CVE-2021-46828
In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections. En libtirpc versiones anteriores a 1.3.3rc1, los atacantes remotos podían agotar los descriptores de archivo de un proceso que usa libtirpc porque las conexiones TCP inactivas son manejadas inapropiadamente. Esto puede, a su vez, conllevar a un bucle infinito svc_run sin aceptar nuevas conexiones A denial of service (DoS) vulnerability was found in libtirpc. This flaw allows a remote attacker to exhaust the file descriptors of a process that uses libtirpc due to mishandling idle TCP connections. • http://git.linux-nfs.org/?p=steved/libtirpc.git%3Ba=commit%3Bh=86529758570cef4c73fb9b9c4104fdc510f701ed https://lists.debian.org/debian-lts-announce/2022/08/msg00004.html https://security.gentoo.org/glsa/202210-33 https://security.netapp.com/advisory/ntap-20221007-0004 https://www.debian.org/security/2022/dsa-5200 https://access.redhat.com/security/cve/CVE-2021-46828 https://bugzilla.redhat.com/show_bug.cgi?id=2109352 • CWE-400: Uncontrolled Resource Consumption CWE-755: Improper Handling of Exceptional Conditions CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

An infinite loop vulnerability was found in libtirpc before version 1.0.2-rc2. With the port to using poll rather than select, exhaustion of file descriptors would cause the server to enter an infinite loop, consuming a large amount of CPU time and denying service to other clients until restarted. Se ha encontrado una vulnerabilidad de bucle infinito en libtirpc en versiones anteriores a la 1.0.2-rc2. Con el puerto para utilizar poll en lugar de select, el agotamiento de los descriptores de archivo podrían provocar que el servidor entre en un bucle infinito, consumiendo una gran cantidad de tiempo de CPU y denegando el servicio a otros clientes hasta que se reinicie. • http://git.linux-nfs.org/?p=steved/libtirpc.git%3Ba=commit%3Bh=fce98161d9815ea016855d9f00274276452c2c4b https://bugzilla.novell.com/show_bug.cgi?id=968175 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14621 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
