The 'podman quadlet install --replace' command does not properly truncate the destination file when the initial reflink copy attempt fails, potentially preserving security-related options from the original Quadlet file. This could lead to undesirable behavior if the preserved options are valid and used by the new Quadlet file. The command opens the existing destination file with O_CREATE|O_WRONLY but omit [truncated]

A flaw was found in sblim-cmpi-base. Insecure temporary file creation in the provider registration scripts allows a local unprivileged user to perform a symlink attack. By creating a symlink in a world-writable directory, an attacker can redirect privileged writes to an arbitrary file during script execution in a privileged context. This can lead to the overwrite of root-owned files, potentially disruptin [truncated]
A local, low-privileged attacker can exploit a race condition during privileged instance migration by manipulating a temporary file in the `/tmp` directory. By repeatedly recreating a symbolic link, the attacker can redirect privileged output to an arbitrary file. This can lead to privileged file corruption or a denial of service (DoS) on the system.
A local attacker with access to the system can exploit an unsafe deserialization vulnerability in the provider-manager's inter-process communication (IPC) message parsing. By sending a specially crafted message, the attacker can cause out-of-bounds memory access, leading to the termination of the provider-manager process and a denial of service. This could also potentially result in limited unintended inf [truncated]

Organizations using search-v2-api should be aware of this vulnerability and take steps to miti [truncated]
A flaw was found in open-iscsi's iscsiuio component. This vulnerability involves an integer underflow and out-of-bounds read during Dynamic Host Configuration Protocol for IPv6 (DHCPv6) packet parsing. Specifically, crafted DHCPv6 Advertise traffic with a short User Datagram Protocol (UDP) length can cause the DHCPv6 payload length to underflow. An unauthenticated attacker on an adjacent network segment c [truncated]
A flaw was found in open-iscsi. This vulnerability allows a remote attacker on the same local network segment to cause a Denial of Service (DoS) in the iscsiuio daemon. By sending a specially crafted Internet Control Message Protocol version 6 (ICMPv6) Router Advertisement with a zero-length option, the attacker can trigger an infinite loop. This leads to sustained CPU usage, rendering the daemon unrespon [truncated]
A flaw in the rsyslog imptcp module can cause rsyslogd to crash due to a crafted input sequence during oversize-frame recovery. This high-severity vulnerability has no identified confidentiality, integrity, privilege escalation, or code execution impacts. System administrators and security teams should prioritize verifying exposure and applying patches or mitigations to prevent potential service disruptio [truncated]
An authorization bypass vulnerability was found in the provider-credential-controller component of multicluster-engine (MCE). An attacker with specific permissions on the hub cluster and knowledge of a prior credential value could exploit this vulnerability by manipulating `copiedFrom` labels to intercept newly rotated provider credentials, leading to unauthorized information disclosure.
A symlink following vulnerability was found in KubeVirt's virt-handler migration proxy. During live migration, virt-handler dials Unix sockets inside the target virt-launcher pod via /proc/<pid>/root/ paths using net.Dial() without symlink protection. These socket paths reside in qemu-owned directories writable by the virt-launcher user. An attacker with namespace edit and pods/exec permissions can replac [truncated]
A local user can create a ClusterCurator resource to escalate privileges from namespace-local access to cluster-wide control, granting broad permissions. This vulnerability affects the cluster-curator-controller component, allowing privilege escalation through a specific naming convention. It has a critical CVSS score of 9.9 and requires immediate attention. Defenders should verify affected product deploy [truncated]
The cluster-curator-controller component of multicluster engine (MCE) is vulnerable to arbitrary Job specification injection due to insufficient validation of user-controlled input.

Successful exploitation could lead to arbitrary code execution and privilege escalatio [truncated]
The multicloud-operators-subscription component of Red Hat Advanced Cluster Management (RHACM) is affected by a vulnerability that allows a namespace-admin tenant to perform a confused-deputy attack. This attack enables the tenant to deploy arbitrary cluster-scoped resources, leading to privilege escalation and potential arbitrary code execution across the cluster. Organizations should be aware of this vu [truncated]
Multiple Use-After-Free vulnerabilities were found in the add_archive_element function in ld/ldmain.c of the GNU linker (ld), a component of binutils. The vulnerability is triggered when LTO plugins are active and the input object has abfd->my_archive == NULL. This flaw can cause a denial of service (linker crash via segmentation fault) and potentially allow for arbitrary code execution through heap manip [truncated]

The exposure of sensitive credentials in logs poses a significant risk to Red Hat clou [truncated]
A flaw was found in acm-search-v2-api-rhel9. When the `getFederationConfig` function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure.
