CVSS: 7.8EPSS: 0%CPEs: 20EXPL: 1CVE-2018-16865 – systemd: stack overflow when receiving many journald entries
https://notcve.org/view.php?id=CVE-2018-16865
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. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald 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 se envían muchas entradas al socket de journal. Un atacante local, o uno remoto si se emplea systemd-journal-remote, podría emplear este error para provocar el cierre inesperado de systemd-journald o ejecutar código con privilegios de journald. • http://packetstormsecurity.com/files/152841/System-Down-A-systemd-journald-Exploit.html http://seclists.org/fulldisclosure/2019/May/21 http://www.openwall.com/lists/oss-security/2019/05/10/4 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/106525 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 • CWE-770: Allocation of Resources Without Limits or Throttling •

An option injection flaw has been discovered in git when it recursively clones a repository with sub-modules. A remote attacker may configure a malicious repository and trick a user into recursively cloning it, thus executing arbitrary commands on the victim's machine. • https://www.exploit-db.com/exploits/45631 https://www.exploit-db.com/exploits/45548 https://github.com/AnonymKing/CVE-2018-17456 https://github.com/matlink/CVE-2018-17456 https://github.com/shpik-kr/CVE-2018-17456 https://github.com/799600966/CVE-2018-17456 https://github.com/KKkai0315/CVE-2018-17456 http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://packetstormsecurity.com/files/152173/Sourcetree-Git-Arbitrary-Code-Execution-URL-Handling.html http:/ • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

CVSS: 7.8EPSS: 1%CPEs: 152EXPL: 0CVE-2018-5391 – The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets
https://notcve.org/view.php?id=CVE-2018-5391
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size. El kernel de Linux en versiones a partir de la 3.9 es vulnerable a un ataque de denegación de servicio (DoS) con tasas bajas de paquetes especialmente modificados que apuntan hacia el reensamblado de fragmentos de IP. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/105108 http://www.securitytracker.com/id/1041476 http://www.securitytracker.com/id/1041637 https://access.redhat.co • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
