https://notcve.org/view.php?id=CVE-2018-20685
In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. En OpenSSH 7.9, scp.c en el cliente scp permite que los servidores SSH omitan las restricciones de acceso planeadas mediante un nombre de archivo "." o un nombre de archivo vacío. El impacto consiste en modificar los permisos del directorio objetivo en el lado del cliente. • http://www.securityfocus.com/bid/106531 https://access.redhat.com/errata/RHSA-2019:3702 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/scp.c.diff?r1=1.197&r2=1.198&f=h https://github.com/openssh/openssh-portable/commit/6010c0303a422a9c5fa8860c061bf7105eb7f8b2 https://lists.debian.org/debian-lts-announce/2019/03/msg00030.html https://security.gentoo.org/glsa/201903-16 https://security.gentoo.org/glsa/202007- • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 1CVE-2018-16864 – systemd: stack overflow when calling syslog from a command with long cmdline
https://notcve.org/view.php?id=CVE-2018-16864
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable. Se ha descubierto una asignación de memoria sin límites, que podría resultar en que la pila choque con otra región de memoria, en systemd-journald, cuando un programa con argumentos largos de la línea de comandos llama a syslog. Un atacante local podría emplear este error para provocar el cierre inesperado de systemd-journald o escalar sus privilegios. • http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/106523 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0049 https://access.redhat.com/errata/RHSA-2019:0204 https://access.redhat.com/errata/RHSA-2019:0271 https://access.redhat.com/errata/RHSA-2019:0342 https://access.redhat.com/errata/RHSA-2019:0361 https://access.redhat.com/errata/RHSA-2019:2402 https://bugzilla.redhat.com/show_ • CWE-770: Allocation of Resources Without Limits or Throttling •

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket.
