CVE-2021-42717
https://notcve.org/view.php?id=CVE-2021-42717
ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4. ModSecurity versiones 3.x hasta 3.0.5, maneja inapropiadamente los objetos JSON excesivamente anidados. • https://github.com/EkamSinghWalia/Detection-and-Mitigation-script-for-CVE-2021-42717 https://lists.debian.org/debian-lts-announce/2022/05/msg00042.html https://www.debian.org/security/2021/dsa-5023 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/modsecurity-dos-vulnerability-in-json-parsing-cve-2021-42717 • CWE-674: Uncontrolled Recursion •
CVE-2021-3772 – kernel: sctp: Invalid chunks may be used to remotely remove existing associations
https://notcve.org/view.php?id=CVE-2021-3772
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. Se ha encontrado un fallo en la pila SCTP de Linux. Un atacante ciego puede ser capaz de matar una asociación SCTP existente mediante trozos no válidos si el atacante conoce las direcciones IP y los números de puerto que están siendo usados y el atacante puede enviar paquetes con direcciones IP falsas • https://bugzilla.redhat.com/show_bug.cgi?id=2000694 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=32f8807a48ae55be0e76880cfe8607a18b5bb0df https://github.com/torvalds/linux/commit/32f8807a48ae55be0e76880cfe8607a18b5bb0df https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://security.netapp.com/advisory/ntap-20221007-0001 https://ubuntu.com/security/CVE-2021-3772 https://www.debian.org/security/2022/dsa-5096 https://www.oracle.com/security-alerts/cp • CWE-354: Improper Validation of Integrity Check Value •

CVE-2021-43976 – kernel: mwifiex_usb_recv() in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker to cause DoS via crafted USB device
https://notcve.org/view.php?id=CVE-2021-43976
In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic). En el kernel de Linux versiones hasta 5.15.2, la función mwifiex_usb_recv en el archivo drivers/net/wireless/marvell/mwifiex/usb.c permite a un atacante (que puede conectar un dispositivo USB diseñado) causar una denegación de servicio (skb_over_panic) A denial of service flaw was found in mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c in the usb subsystem of the Linux kernel. This is due to a missing clean-up for a malfunctioning usb device with an unknown recv_type. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=04d80663f67ccef893061b49ec8a42ff7045ae84 https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X24M7KDC4OJOZNS3RDSYC7ELNELOLQ2N https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YODMYMGZYDXQKGJGX7TJG4XV4L5YLLBD https://patchwork.kernel.org/projec • CWE-459: Incomplete Cleanup •
