CVSS: 5.5EPSS: 0%CPEs: 13EXPL: 0CVE-2020-10685 – Ansible: modules which use files encrypted with vault are not properly cleaned up
https://notcve.org/view.php?id=CVE-2020-10685
A flaw was found in Ansible Engine affecting Ansible Engine versions 2.7.x before 2.7.17 and 2.8.x before 2.8.11 and 2.9.x before 2.9.7 as well as Ansible Tower before and including versions 3.4.5 and 3.5.5 and 3.6.3 when using modules which decrypts vault files such as assemble, script, unarchive, win_copy, aws_s3 or copy modules. The temporary directory is created in /tmp leaves the s ts unencrypted. On Operating Systems which /tmp is not a tmpfs but part of the root partition, the directory is only cleared on boot and the decryp emains when the host is switched off. The system will be vulnerable when the system is not running. So decrypted data must be cleared as soon as possible and the data which normally is encrypted ble. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10685 https://github.com/ansible/ansible/pull/68433 https://security.gentoo.org/glsa/202006-11 https://www.debian.org/security/2021/dsa-4950 https://access.redhat.com/security/cve/CVE-2020-10685 https://bugzilla.redhat.com/show_bug.cgi?id=1814627 • CWE-459: Incomplete Cleanup •
CVSS: 7.9EPSS: 0%CPEs: 12EXPL: 0CVE-2020-10684 – Ansible: code injection when using ansible_facts as a subkey
https://notcve.org/view.php?id=CVE-2020-10684
A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x prior to 2.7.17, 2.8.9 and 2.9.6 respectively, when using ansible_facts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansible_facts after the clean. An attacker could take advantage of this by altering the ansible_facts, such as ansible_hosts, users and any other key data which would lead into privilege escalation or code injection. Se descubrió un fallo en Ansible Engine, todas las versiones 2.7.x, 2.8.x y versiones 2.9.x anteriores a las versiones 2.7.17, 2.8.9 y 2.9.6 respectivamente, cuando se usa la función ansible_facts como una subclave de sí mismo y se promociona hacia una variable cuando la inyección está habilitada, sobrescribe los ansible_facts después de la limpieza. Un atacante podría tomar ventaja de esto alterando la función ansible_facts, como ansible_hosts, los usuarios y cualquier otro dato clave que conllevar a una escalada de privilegios o una inyección de código. A flaw was found in the Ansible Engine. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10684 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/WQVOQD4VAIXXTVQAJKTN7NUGTJFE2PCB https://security.gentoo.org/glsa/202006-11 https://www.debian.org/security/2021/dsa-4950 https:// • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-862: Missing Authorization •
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.

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 •
