https://notcve.org/view.php?id=CVE-2019-14444
apply_relocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to trigger a write access violation (in byte_put_little_endian function in elfcomm.c) via an ELF file, as demonstrated by readelf. La función apply_relocations en el archivo readelf.c en Binutils de GNU versión 2.32, contiene un desbordamiento de enteros que permite a los atacantes desencadenar una violación de acceso de escritura (en la función byte_put_little_endian en el archivo elfcomm.c) por medio de un archivo ELF, como es demostrado por readelf. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00078.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00004.html https://security.gentoo.org/glsa/202007-39 https://security.netapp.com/advisory/ntap-20190822-0002 https://sourceware.org/bugzilla/show_bug.cgi?id=24829 https://usn.ubuntu.com/4336-1 • CWE-190: Integer Overflow or Wraparound •

CVE-2019-13272 – Linux Kernel Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2019-13272
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. En el kernel de Linux anterior a versión 5.1.17, ptrace_link en el archivo kernel/ptrace.c maneja inapropiadamente la grabación de las credenciales de un proceso que desea crear una relación de ptrace, que permite a los usuarios locales obtener acceso de root aprovechando determinados escenarios con un relación de proceso padre-hijo, donde un padre elimina los privilegios y llama a execve (permitiendo potencialmente el control por parte de un atacante). • https://www.exploit-db.com/exploits/47133 https://www.exploit-db.com/exploits/47163 https://www.exploit-db.com/exploits/50541 https://www.exploit-db.com/exploits/47543 https://github.com/jas502n/CVE-2019-13272 https://github.com/Cyc1eC/CVE-2019-13272 https://github.com/oneoy/CVE-2019-13272 https://github.com/polosec/CVE-2019-13272 https://github.com/MDS1GNAL/ptrace_scope-CVE-2019-13272-privilege-escalation https://github.com/datntsec/CVE-2019-13272 https://github • CWE-271: Privilege Dropping / Lowering Errors •

An issue was discovered in get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup_const of node_info->vdev_port.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). Se descubrió un problema en get_vdev_port_node_info en arch / sparc / kernel / mdesc.c en el kernel de Linux hasta la versión 5.1.6. Hay un kstrdup_const sin marcar de node_info-> vdev_port.name, que podría permitir que un atacante provoque una denegación de servicio (desreferencia de puntero NULL y bloqueo del sistema). • http://www.securityfocus.com/bid/108549 https://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc.git/commit/?id=80caf43549e7e41a695c6d1e11066286538b336f https://security.netapp.com/advisory/ntap-20190710-0002 https://support.f5.com/csp/article/K60924046 https://support.f5.com/csp/article/K60924046?utm_source=f5support&%3Butm_medium=RSS https://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg2014901.html • CWE-476: NULL Pointer Dereference •
