CVE-2021-20191 – ansible: multiple modules expose secured values
https://notcve.org/view.php?id=CVE-2021-20191
A flaw was found in ansible. Credentials, such as secrets, are being disclosed in console log by default and not protected by no_log feature when using those modules. An attacker can take advantage of this information to steal those credentials. The highest threat from this vulnerability is to data confidentiality. Versions before ansible 2.9.18 are affected. • https://bugzilla.redhat.com/show_bug.cgi?id=1916813 https://lists.debian.org/debian-lts-announce/2023/12/msg00018.html https://access.redhat.com/security/cve/CVE-2021-20191 • CWE-532: Insertion of Sensitive Information into Log File •
CVE-2020-14340 – xnio: file descriptor leak caused by growing amounts of NIO Selector file handles may lead to DoS
https://notcve.org/view.php?id=CVE-2020-14340
A vulnerability was discovered in XNIO where file descriptor leak caused by growing amounts of NIO Selector file handles between garbage collection cycles. It may allow the attacker to cause a denial of service. It affects XNIO versions 3.6.0.Beta1 through 3.8.1.Final. Se detectó una vulnerabilidad en XNIO en la que se produce un filtrado de descriptores de archivos causada por el crecimiento de la cantidad de manejadores de archivos NIO Selector entre los ciclos de recolección de basura. Puede permitir al atacante causar una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1860218 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-14340 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-10775 – ovirt-engine: Redirect to arbitrary URL allows for phishing
https://notcve.org/view.php?id=CVE-2020-10775
An Open redirect vulnerability was found in ovirt-engine versions 4.4 and earlier, where it allows remote attackers to redirect users to arbitrary web sites and attempt phishing attacks. Once the target has opened the malicious URL in their browser, the critical part of the URL is no longer visible. The highest threat from this vulnerability is on confidentiality. Se detectó una vulnerabilidad de redireccionamiento Abierto en ovirt-engine versiones 4.4 y anteriores , donde permite a atacantes remotos redireccionar a usuarios a sitios web arbitrarios e intentar ataques de phishing. Una vez que el objetivo ha abierto la URL maliciosa en su navegador, la parte crítica de la URL ya no es visible. • https://bugzilla.redhat.com/show_bug.cgi?id=1847420 https://access.redhat.com/security/cve/CVE-2020-10775 • CWE-451: User Interface (UI) Misrepresentation of Critical Information CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVE-2019-11135 – hw: TSX Transaction Asynchronous Abort (TAA)
https://notcve.org/view.php?id=CVE-2019-11135
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. Una condición de tipo TSX Asynchronous Abort en algunas CPU que utilizan ejecución especulativa puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un canal lateral con acceso local. A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/10/3 http://www.openwall.com/lists/oss-security/2019/12/10/4 http://www.openwall.com/lists/oss-security/2019/12 • CWE-203: Observable Discrepancy •
CVE-2019-14821 – Kernel: KVM: OOB memory access via mmio ring buffer
https://notcve.org/view.php?id=CVE-2019-14821
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. Se encontró un problema de acceso fuera de límites en el kernel de Linux, todas las versiones hasta 5.3, en la manera en que el hipervisor KVM del kernel de Linux implementa la operación de escritura MMIO Coalesced. Opera en un objeto MMIO ring buffer "struct kvm_coalesced_mmio", en donde los índices de escritura "ring-)first" y "ring-)last" podrían ser suministrados por un proceso de espacio de usuario del host. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/09/20/1 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 • CWE-787: Out-of-bounds Write •
