https://notcve.org/view.php?id=CVE-2023-6779
An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer.

A heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when the openlog function was not called, or called with the ident argument set to NULL, and the program name (the basename of argv[0]) is bigger than 1024 bytes, resulting in an application crash or local privilege escalation.

https://notcve.org/view.php?id=CVE-2024-0567
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack.

https://notcve.org/view.php?id=CVE-2024-0553
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.

CVSS: 6.8EPSS: 0%CPEs: 4EXPL: 0CVE-2023-4001 – Grub2: bypass the grub password protection feature
https://notcve.org/view.php?id=CVE-2023-4001
An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package. Se encontró un fallo de omisión de autenticación en GRUB debido a la forma en que GRUB usa el UUID de un dispositivo para buscar el archivo de configuración que contiene el hash de contraseña para la función de protección de contraseña de GRUB. Un atacante capaz de conectar una unidad externa, como una memoria USB que contenga un sistema de archivos con un UUID duplicado (el mismo que en el sistema de archivos "/boot/") puede omitir la función de protección con contraseña GRUB en los sistemas UEFI, que enumeran unidades extraíbles. antes que los no removibles. • http://www.openwall.com/lists/oss-security/2024/01/15/3 https://access.redhat.com/errata/RHSA-2024:0437 https://access.redhat.com/errata/RHSA-2024:0456 https://access.redhat.com/errata/RHSA-2024:0468 https://access.redhat.com/security/cve/CVE-2023-4001 https://bugzilla.redhat.com/show_bug.cgi?id=2224951 https://dfir.ru/2024/01/15/cve-2023-4001-a-vulnerability-in-the-downstream-grub-boot-manager https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject& • CWE-290: Authentication Bypass by Spoofing •
