CVSS: 6.8EPSS: 0%CPEs: 15EXPL: 0CVE-2022-3916 – Keycloak: session takeover with oidc offline refreshtokens
https://notcve.org/view.php?id=CVE-2022-3916
A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user. Se encontró una falla en el alcance offline_access en Keycloak. Este problema afectaría más a los usuarios de ordenadores compartidos (especialmente si las cookies no se borran), debido a la falta de validación de la sesión root y a la reutilización de los identificadores de sesión en las sesiones de autenticación de usuario y root. • https://access.redhat.com/errata/RHSA-2022:8961 https://access.redhat.com/errata/RHSA-2022:8962 https://access.redhat.com/errata/RHSA-2022:8963 https://access.redhat.com/errata/RHSA-2022:8964 https://access.redhat.com/errata/RHSA-2022:8965 https://access.redhat.com/errata/RHSA-2023:1043 https://access.redhat.com/errata/RHSA-2023:1044 https://access.redhat.com/errata/RHSA-2023:1045 https://access.redhat.com/errata/RHSA-2023:1047 https://access.redhat.com/errata/RHSA • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •
CVSS: 6.9EPSS: 0%CPEs: 40EXPL: 0CVE-2021-3696 – grub2: Crafted PNG image may lead to out-of-bound write during huffman table handling
https://notcve.org/view.php?id=CVE-2021-3696
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Puede producirse una escritura fuera de límites de la pila durante el manejo de las tablas Huffman en el lector PNG. • https://bugzilla.redhat.com/show_bug.cgi?id=1991686 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3696 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-3697
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Una imagen JPEG diseñada puede conllevar que el lector de JPEG desborde su puntero de datos, permitiendo que los datos controlados por el usuario sean escritos en la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991687 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3697 • CWE-787: Out-of-bounds Write •
