CVE-2022-1227 – psgo: Privilege escalation in 'podman top'
https://notcve.org/view.php?id=CVE-2022-1227
A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem, leading to information disclosure or denial of service. Se ha encontrado un fallo de escalada de privilegios en Podman. • https://bugzilla.redhat.com/show_bug.cgi?id=2070368 https://github.com/containers/podman/issues/10941 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://security.netapp.com/advisory/ntap-20240628-0001 https://access.redhat.com/security/cve/CVE-2022-1227 • CWE-269: Improper Privilege Management CWE-281: Improper Preservation of Permissions •
CVE-2022-0852 – convert2rhel: Red Hat account password passed via command line by code
https://notcve.org/view.php?id=CVE-2022-0852
There is a flaw in convert2rhel. convert2rhel passes the Red Hat account password to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the password via the process command line via e.g. htop or ps. The specific impact varies upon the privileges of the Red Hat account in question, but it could affect the integrity, availability, and/or data confidentiality of other systems that are administered by that account. This occurs regardless of how the password is supplied to convert2rhel. Se presentan un fallo en convert2rhel. convert2rhel pasa la contraseña de la cuenta de Red Hat a subscription-manager por medio de la línea de comandos, lo que podría permitir a usuarios no autorizados localmente en la máquina visualizar la contraseña por medio de la línea de comandos del proceso, por ejemplo, htop o ps. El impacto específico varía según los privilegios de la cuenta de Red Hat en cuestión, pero podría afectar la integridad, disponibilidad y/o confidencialidad de los datos de otros sistemas que son administrados por esa cuenta. • https://access.redhat.com/security/cve/CVE-2022-0852 https://bugzilla.redhat.com/show_bug.cgi?id=2060129 https://github.com/oamg/convert2rhel/commit/8d72fb030ed31116fdb256b327d299337b000af4 https://github.com/oamg/convert2rhel/pull/492 https://issues.redhat.com/browse/RHELC-432 • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor CWE-668: Exposure of Resource to Wrong Sphere •
