CVE-2023-7216 – Cpio: extraction allows symlinks which enables remote command execution
https://notcve.org/view.php?id=CVE-2023-7216
A path traversal vulnerability was found in the CPIO utility. This issue could allow a remote unauthenticated attacker to trick a user into opening a specially crafted archive. During the extraction process, the archiver could follow symlinks outside of the intended directory, which allows files to be written in arbitrary directories through symlinks. Se encontró una vulnerabilidad de path traversal en la utilidad CPIO. Este problema podría permitir que un atacante remoto no autenticado engañe a un usuario para que abra un archivo especialmente manipulado. • https://access.redhat.com/security/cve/CVE-2023-7216 https://bugzilla.redhat.com/show_bug.cgi?id=2249901 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2023-6240 – Kernel: marvin vulnerability side-channel leakage in the rsa decryption operation
https://notcve.org/view.php?id=CVE-2023-6240
A Marvin vulnerability side-channel leakage was found in the RSA decryption operation in the Linux Kernel. This issue may allow a network attacker to decrypt ciphertexts or forge signatures, limiting the services that use that private key. Se encontró una fuga de canal lateral de vulnerabilidad de Marvin en la operación de descifrado RSA en el kernel de Linux. Este problema puede permitir que un atacante de red descifre textos cifrados o falsifique firmas, limitando los servicios que utilizan esa clave privada. • https://access.redhat.com/errata/RHSA-2024:1881 https://access.redhat.com/errata/RHSA-2024:1882 https://access.redhat.com/errata/RHSA-2024:2758 https://access.redhat.com/errata/RHSA-2024:3414 https://access.redhat.com/errata/RHSA-2024:3421 https://access.redhat.com/errata/RHSA-2024:3618 https://access.redhat.com/errata/RHSA-2024:3627 https://access.redhat.com/security/cve/CVE-2023-6240 https://bugzilla.redhat.com/show_bug.cgi?id=2250843 https://people.redhat.com/ • CWE-203: Observable Discrepancy •
CVE-2023-5992 – Opensc: side-channel leaks while stripping encryption pkcs#1 padding
https://notcve.org/view.php?id=CVE-2023-5992
A vulnerability was found in OpenSC where PKCS#1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data.

CVE-2024-0914 – Opencryptoki: timing side-channel in handling of rsa pkcs#1 v1.5 padded ciphertexts (marvin)
https://notcve.org/view.php?id=CVE-2024-0914
A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key. Se descubrió una vulnerabilidad de canal lateral de temporización en el paquete opencryptoki mientras se procesan textos cifrados acolchados RSA PKCS#1 v1.5. Este fallo podría potencialmente permitir el descifrado o la firma de texto cifrado RSA no autorizado, incluso sin acceso a la clave privada correspondiente. • https://access.redhat.com/errata/RHSA-2024:1239 https://access.redhat.com/errata/RHSA-2024:1411 https://access.redhat.com/errata/RHSA-2024:1608 https://access.redhat.com/errata/RHSA-2024:1856 https://access.redhat.com/errata/RHSA-2024:1992 https://access.redhat.com/security/cve/CVE-2024-0914 https://bugzilla.redhat.com/show_bug.cgi?id=2260407 https://people.redhat.com/~hkario/marvin • CWE-203: Observable Discrepancy •
CVE-2024-0564 – Kernel: max page sharing of kernel samepage merging (ksm) may cause memory deduplication
https://notcve.org/view.php?id=CVE-2024-0564
A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page. • https://access.redhat.com/security/cve/CVE-2024-0564 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680513 https://bugzilla.redhat.com/show_bug.cgi?id=2258514 https://link.springer.com/conference/wisa https://wisa.or.kr/accepted • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') CWE-203: Observable Discrepancy •
