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 •

https://notcve.org/view.php?id=CVE-2021-3935
When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1. Cuando PgBouncer está configurado para usar la autenticación "cert", un atacante de tipo "man-in-the-middle" puede inyectar consultas SQL arbitrarias cuando se establece una conexión por primera vez, a pesar del uso de la verificación y el cifrado de certificados TLS.

CVE-2021-3941
https://notcve.org/view.php?id=CVE-2021-3941
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. En la rutina RGBtoXYZ() del archivo ImfChromaticities.cpp, se presentan algunas operaciones de división como "float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;" y "chroma.green.y * (X + Z)) / d;" pero no es comprobado que el divisor tenga un valor 0.
