CVSS: 5.0EPSS: 0%CPEs: 14EXPL: 1CVE-2020-1733 – ansible: insecure temporary directory when running become_user from become directive
https://notcve.org/view.php?id=CVE-2020-1733
A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p <dir>"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/<pid>/cmdline'. Se encontró un fallo de condición de carrera en Ansible Engine versiones 2.7.17 y anteriores, 2.8.9 y anteriores, 2.9.6 y anteriores, cuando se ejecuta un playbook con un usuario convertido a no privilegiado. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1733 https://github.com/ansible/ansible/issues/67791 https://lists.debian.org/debian-lts-announce/2020/05/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DKPA4KC3OJSUFASUYMG66HKJE7ADNGFW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MRRYUU5ZBLPBXCYG6CFP35D64NP2UB2S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WQVOQD4VAIXXTVQAJK • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-377: Insecure Temporary File •
CVSS: 7.7EPSS: 0%CPEs: 8EXPL: 0CVE-2020-1711 – QEMU: block: iscsi: OOB heap access via an unexpected response of iSCSI Server
https://notcve.org/view.php?id=CVE-2020-1711
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host. Se detectó una fallo de acceso al búfer de la pila fuera de límites en la manera en que el controlador de iSCSI Block versiones 2.xx de QEMU hasta 2.12.0 incluyéndola, manejó una respuesta proveniente de un servidor iSCSI mientras se comprobaba el estado de un Logical Address Block (LBA) en una rutina iscsi_co_block_status(). Un usuario remoto podría usar este fallo para bloquear el proceso de QEMU, resultando en una denegación de servicio o posible ejecución de código arbitrario con privilegios del proceso de QEMU en el host.

CVSS: 7.3EPSS: 0%CPEs: 10EXPL: 0CVE-2019-14905 – Ansible: malicious code could craft filename in nxos_file_copy module
https://notcve.org/view.php?id=CVE-2019-14905
A vulnerability was found in Ansible Engine versions 2.9.x before 2.9.3, 2.8.x before 2.8.8, 2.7.x before 2.7.16 and earlier, where in Ansible's nxos_file_copy module can be used to copy files to a flash or bootflash on NXOS devices. Malicious code could craft the filename parameter to perform OS command injections. This could result in a loss of confidentiality of the system among other issues. Se detectó una vulnerabilidad en Ansible Engine versiones 2.9.x anteriores a 2.9.3, versiones 2.8.x anteriores a 2.8.8, versiones 2.7.x anteriores a 2.7.16 y anteriores, donde en el módulo nxos_file_copy de Ansible puede ser usado para copiar archivos a una flash o bootflash en dispositivos NXOS.

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 •
