CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2020-1712 – systemd: use-after-free when asynchronous polkit queries are performed
https://notcve.org/view.php?id=CVE-2020-1712
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages. Se detectó una vulnerabilidad uso de la memoria previamente liberada de la pila en systemd versiones anteriores a v245-rc1, donde se llevaron a cabo consultas de Polkit asincrónicas mientras se manejan mensajes dbus. Un atacante no privilegiado local puede abusar de este fallo para bloquear los servicios de systemd o potencialmente ejecutar código y elevar sus privilegios, mediante el envío de mensajes dbus especialmente diseñados. A heap use-after-free vulnerability was found in systemd, where asynchronous Polkit queries are performed while handling dbus messages. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1712 https://github.com/systemd/systemd/commit/1068447e6954dc6ce52f099ed174c442cb89ed54 https://github.com/systemd/systemd/commit/637486261528e8aa3da9f26a4487dc254f4b7abb https://github.com/systemd/systemd/commit/bc130b6858327b382b07b3985cf48e2aa9016b2d https://github.com/systemd/systemd/commit/ea0d0ede03c6f18dbc5036c5e9cccf97e415ccc2 https://lists.debian.org/debian-lts-announce/2022/06/msg00025.html https://www.openwall.com/lists/oss-security/2020/02/05/1 https://access.redhat.c • CWE-416: Use After Free •
CVSS: 9.1EPSS: 0%CPEs: 8EXPL: 2CVE-2019-14859 – python-ecdsa: DER encoding is not being verified in signatures
https://notcve.org/view.php?id=CVE-2019-14859
A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions. Se encontró un fallo en todas las versiones de python-ecdsa anteriores a la versión 0.13.3, donde no se comprobaba correctamente si las firmas usaban codificación DER. Sin esta comprobación, se podría aceptar una firma malformada, haciendo que la firma sea maleable. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14859 https://github.com/warner/python-ecdsa/issues/114 https://github.com/warner/python-ecdsa/releases/tag/python-ecdsa-0.13.3 https://pypi.org/project/ecdsa/0.13.3 https://access.redhat.com/security/cve/CVE-2019-14859 https://bugzilla.redhat.com/show_bug.cgi?id=1760843 • CWE-347: Improper Verification of Cryptographic Signature •

https://notcve.org/view.php?id=CVE-2018-10875
A flaw was found in ansible. ansible.cfg is read from the current working directory which can be altered to make it point to a plugin or a module path under the control of an attacker, thus allowing the attacker to execute arbitrary code. Se ha encontrado un error en ansible. ansible.cfg se lee desde el directorio de trabajo actual, que puede alterarse para hacer que señale a un plugin o una ruta de módulo bajo el control de un atacante, permitiendo que el atacante ejecute código arbitrario. It was found that ansible.cfg is being read from the current working directory, which can be made to point to plugin or module paths that are under control of the attacker.

CVSS: 6.1EPSS: 0%CPEs: 15EXPL: 0CVE-2018-1059 – dpdk: Information exposure in unchecked guest physical to host virtual address translations
https://notcve.org/view.php?id=CVE-2018-1059
The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions before 18.02.1 are vulnerable. La interfaz vhost de usuario de DPDK no verifica que el rango físico invitado solicitado esté mapeado y sea contiguo al realizar traducciones de direcciones físicas de invitado a direcciones virtuales del host. Esto podría conducir a que un invitado malicioso exponga la memoria del proceso del backend del usuario vhost. • https://access.redhat.com/errata/RHSA-2018:1267 https://access.redhat.com/errata/RHSA-2018:2038 https://access.redhat.com/errata/RHSA-2018:2102 https://access.redhat.com/errata/RHSA-2018:2524 https://access.redhat.com/security/cve/cve-2018-1059 https://bugzilla.redhat.com/show_bug.cgi?id=1544298 https://usn.ubuntu.com/3642-1 https://usn.ubuntu.com/3642-2 https://access.redhat.com/security/cve/CVE-2018-1059 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
