An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR. This is a different flaw from CVE-2021-23215. Se encontró un desbordamiento de enteros que conlleva un desbordamiento del búfer de la pila en el DwaCompressor de OpenEXR en versiones anteriores a 3.0.1. Un atacante podría usar este fallo para bloquear una aplicación compilada con OpenEXR. • https://bugzilla.redhat.com/show_bug.cgi?id=1947582 https://lists.debian.org/debian-lts-announce/2021/07/msg00001.html https://lists.debian.org/debian-lts-announce/2022/12/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BXFLD4ZAXKAIWO6ZPBCQEEDZB5IG676K https://www.debian.org/security/2022/dsa-5299 • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •

CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 1CVE-2021-33560 – libgcrypt: mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm
https://notcve.org/view.php?id=CVE-2021-33560
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 •
