https://notcve.org/view.php?id=CVE-2023-4320
An arithmetic overflow flaw was found in Satellite when creating a new personal access token. This flaw allows an attacker who uses this arithmetic overflow to create personal access tokens that are valid indefinitely, resulting in damage to the system's integrity. Se encontró una falla de desbordamiento aritmético en Satellite al crear un nuevo token de acceso personal. Esta falla permite a un atacante que utiliza este desbordamiento aritmético crear tokens de acceso personal que son válidos indefinidamente, lo que daña la integridad del sistema. • https://access.redhat.com/errata/RHSA-2024:2010 https://access.redhat.com/security/cve/CVE-2023-4320 https://bugzilla.redhat.com/show_bug.cgi?id=2231814 • CWE-613: Insufficient Session Expiration •

https://notcve.org/view.php?id=CVE-2023-3430
A vulnerability was found in OpenImageIO, where a heap buffer overflow exists in the src/gif.imageio/gifinput.cpp file. This flaw allows a remote attacker to pass a specially crafted file to the application, which triggers a heap-based buffer overflow and could cause a crash, leading to a denial of service. Se encontró una vulnerabilidad en OpenImageIO, donde existe un desbordamiento de búfer de almacenamiento dinámico en el archivo src/gif.imageio/gifinput.cpp. Este fallo permite que un atacante remoto pase un archivo especialmente manipulado a la aplicación, lo que desencadena un desbordamiento de búfer de almacenamiento dinámico y podría causar una falla, lo que llevaría a una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=2218380 https://github.com/AcademySoftwareFoundation/OpenImageIO/issues/3840 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.

https://notcve.org/view.php?id=CVE-2023-6563
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
