When reading a specially crafted 7Z archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' sevenz package. Al leer un archivo 7Z especialmente diseñado, Compress puede asignar grandes cantidades de memoria que finalmente conllevan a un error de falta de memoria incluso para entradas muy pequeñas.

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding. Apache Tomcat versiones 10.0.0-M1 hasta 10.0.6, versiones 9.0.0.M1 hasta 9.0.46 y versiones 8.5.0 hasta 8.5.66, no analizaban correctamente el encabezado de petición HTTP transfer-encoding en algunas circunstancias, conllevando a la posibilidad de contrabando de peticiones cuando se usaba con un proxy inverso. Específicamente: - Tomcat ignoraba incorrectamente el encabezado de codificación de transferencia si el cliente declaraba que sólo aceptaría una respuesta HTTP/1.0; - Tomcat honraba la codificación de identificación; y - Tomcat no se aseguraba de que, si estaba presente, la codificación en trozos fuera la codificación final • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r290aee55b72811fd19e75ac80f6143716c079170c5671b96932ed44b%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r40f921575aee8d7d34e53182f862c45cbb8f3d898c9d4e865c2ec262%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r612a79269b0d5e5780c62dfd34286a8037232fec0bc6f1a7e60c9381%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/rc6ef52453bb996a98cb45442871a1db56b7c349939e45d829bf9ae37%40%3Ccommits.tomee.apache.org%3E https:/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. curl versiones 7.61.0 hasta 7.76.1, sufre de exposición de un elemento de datos a una sesión equivocada debido a un error en el código para la función CURLOPT_SSL_CIPHER_LIST cuando libcurl es construído para usar la biblioteca TLS de Schannel. El ajuste de cifrado seleccionado se almacenaba en una única variable "static" en la biblioteca, lo que tiene el sorprendente efecto secundario de que si una aplicación establece múltiples transferencias concurrentes, la última que ajusta los cifrados controlará accidentalmente el ajuste usado por todas las transferencias.

Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP. Libgcrypt versiones anteriores a 1.8.8 y versiones 1.9.x anteriores a 1.9.3, maneja inapropiadamente el cifrado de ElGamal porque carece de cegado de exponentes para hacer frente a un ataque de canal lateral contra la función mpi_powm, y el tamaño de la ventana no se elige apropiadamente. Esto, por ejemplo, afecta el uso de ElGamal en OpenPGP. A side-channel attack flaw was found in the way libgcrypt implemented Elgamal encryption. • https://github.com/IBM/PGP-client-checker-CVE-2021-33560 https://dev.gnupg.org/T5305 https://dev.gnupg.org/T5328 https://dev.gnupg.org/T5466 https://dev.gnupg.org/rCe8b7f10be275bcedb5fc05ed4837a89bfd605c61 https://lists.debian.org/debian-lts-announce/2021/06/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BKKTOIGFW2SGN3DO2UHHVZ7MJSYN4AAB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R7OAPCUGPF3VLA7QAJUQSL255D4ITVTL • CWE-203: Observable Discrepancy CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
