https://notcve.org/view.php?id=CVE-2022-1355
A stack buffer overflow flaw was found in Libtiffs' tiffcp.c in main() function. This flaw allows an attacker to pass a crafted TIFF file to the tiffcp tool, triggering a stack buffer overflow issue, possibly corrupting the memory, and causing a crash that leads to a denial of service. Se ha encontrado un fallo de desbordamiento del búfer de la pila en la función main() del archivo tiffcp.c de Libtiffs. Este defecto permite a un atacante pasar un archivo TIFF diseñado a la herramienta tiffcp, desencadenando un problema de desbordamiento del búfer de la pila, posiblemente corrompiendo la memoria, y causando un fallo que conlleva a una denegación de servicio • https://access.redhat.com/security/cve/CVE-2022-1355 https://bugzilla.redhat.com/show_bug.cgi?id=2074415 https://gitlab.com/libtiff/libtiff/-/issues/400 https://gitlab.com/libtiff/libtiff/-/merge_requests/323 https://lists.debian.org/debian-lts-announce/2023/01/msg00018.html https://security.gentoo.org/glsa/202210-10 https://security.netapp.com/advisory/ntap-20221014-0007 https://www.debian.org/security/2023/dsa-5333 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). Se ha encontrado un fallo en el kernel de Linux. La API existente de KVM SEV presenta una vulnerabilidad que permite que una aplicación a nivel de usuario no root (anfitrión) bloquee el kernel del anfitrión al crear una instancia de VM de invitado confidencial en la CPU de AMD que admite la virtualización cifrada segura (SEV). • https://access.redhat.com/security/cve/CVE-2022-0171 https://bugzilla.redhat.com/show_bug.cgi?id=2038940 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=683412ccf61294d727ead4a73d97397396e69a6b https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.debian.org/security/2022/dsa-5257 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer CWE-459: Incomplete Cleanup •

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. Se encontró una vulnerabilidad en el verificador EBPF del kernel de Linux cuando son manejadas estructuras de datos internas. Las ubicaciones de memoria interna podían ser devueltas al espacio de usuario. • https://access.redhat.com/security/cve/CVE-2021-4159 https://bugzilla.redhat.com/show_bug.cgi?id=2036024 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=294f2fc6da27620a506e6c050241655459ccd6bd https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security-tracker.debian.org/tracker/CVE-2021-4159 • CWE-202: Exposure of Sensitive Information Through Data Queries •
