A heap-buffer-overflow vulnerability was found in LibTIFF, in extractImageSection() at tools/tiffcrop.c:7916 and tools/tiffcrop.c:7801. This flaw allows attackers to cause a denial of service via a crafted tiff file. Se encontró un error de lectura fuera de los límites en el paquete gawk de buildin.c. Este problema puede provocar un bloqueo y podría utilizarse para leer información confidencial. • https://access.redhat.com/security/cve/CVE-2023-3164 https://bugzilla.redhat.com/show_bug.cgi?id=2213531 https://gitlab.com/libtiff/libtiff/-/issues/542 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-1192
A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service. Se encontró una falla de use-after-free en smb2_is_status_io_timeout() en CIFS en el kernel de Linux. Después de que CIFS transfiere datos de respuesta a una llamada al sistema, todavía hay puntos variables locales en la región de memoria, y si la llamada al sistema la libera más rápido de lo que CIFS la usa, CIFS accederá a una región de memoria libre, lo que provocará una denegación de servicio. • https://access.redhat.com/security/cve/CVE-2023-1192 https://bugzilla.redhat.com/show_bug.cgi?id=2154178 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d527f51331cace562393a8038d870b3e9916686f • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-5178
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. Se encontró una vulnerabilidad de use-after-free en drivers/nvme/target/tcp.c` en `nvmet_tcp_free_crypto` debido a un error lógico en el subsistema NVMe-oF/TCP en el kernel de Linux. Este problema puede permitir que un usuario malintencionado cause un problema de use-after-free y double-free, lo que puede permitir la ejecución remota de código o provocar una escalada de privilegios locales en caso de que el atacante ya tenga privilegios locales. • https://github.com/rockrid3r/CVE-2023-5178 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7548 https://access.redhat.com/errata/RHSA-2023:7549 https://access.redhat.com/errata/RHSA-2023:7551 https://access.redhat.com/errata/RHSA-2023:7554 https://access.redhat.com/errata/RHSA-2023:7557 https://access.redhat.com/errata/RHSA-2023 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 51EXPL: 0CVE-2023-3972 – Insights-client: unsafe handling of temporary files and directories
https://notcve.org/view.php?id=CVE-2023-3972
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide). Se encontró una vulnerabilidad en insights-client. • https://access.redhat.com/errata/RHSA-2023:6264 https://access.redhat.com/errata/RHSA-2023:6282 https://access.redhat.com/errata/RHSA-2023:6283 https://access.redhat.com/errata/RHSA-2023:6284 https://access.redhat.com/errata/RHSA-2023:6795 https://access.redhat.com/errata/RHSA-2023:6796 https://access.redhat.com/errata/RHSA-2023:6798 https://access.redhat.com/errata/RHSA-2023:6811 https://access.redhat.com/security/cve/CVE-2023-3972 https://bugzilla.redhat.com/show • CWE-379: Creation of Temporary File in Directory with Insecure Permissions CWE-668: Exposure of Resource to Wrong Sphere •
