CVE-2021-20257 – QEMU: net: e1000: infinite loop while processing transmit descriptors
https://notcve.org/view.php?id=CVE-2021-20257
An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

CVE-2021-34558 – golang: crypto/tls: certificate of wrong type is causing TLS client to panic
https://notcve.org/view.php?id=CVE-2021-34558
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic. El paquete crypto/tls de Go versiones hasta 1.16.5, no afirma apropiadamente que el tipo de clave pública en un certificado X.509 coincida con el tipo esperado cuando se hace un intercambio de claves basado en RSA, permitiendo a un servidor TLS malicioso causar el pánico en un cliente TLS A flaw was found in golang. A panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected. • https://golang.org/doc/devel/release#go1.16.minor https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/n9FxMelZGAQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BA7MFVXRBEKRTLSLYDICTYCGEMK2HZ7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3XBQUFVI5TMV4KMKI7GKA223LHGPQISE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6BTC3JQUASFN5U2XA4UZIGAPZQBD5JSS https:/ • CWE-20: Improper Input Validation CWE-295: Improper Certificate Validation •
CVE-2021-36740 – varnish: HTTP/2 request smuggling attack via a large Content-Length header for a POST request
https://notcve.org/view.php?id=CVE-2021-36740
Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8. Varnish Cache, con HTTP/2 habilitado, permite el contrabando de peticiones y la omisión de autorización de VCL por medio de un encabezado Content-Length grande para una petición POST. Esto afecta a Varnish Enterprise versiones 6.0.x anteriores a 6.0.8r3, y Varnish Cache versiones 5.xy 6.x anteriores a 6.5.2, versiones 6.6.x anteriores a 6.6.1 y versiones 6.0 LTS anteriores a 6.0.8 A flaw was found in Varnish.
