A security vulnerability in A flaw (CVSS 4.3). Remediation should follow standard vulnerability management procedures.
GIMP's PSP file parser fails to validate 32-bit length values in the read_creator_block() function, allowing local attackers to trigger integer overflow and heap buffer overflow via specially crafted PSP image files, resulting in application-level denial of service. Red Hat Enterprise Linux versions 6-9, Ubuntu (7 releases), Debian (9 releases), and SUSE are affected. No public exploit code or active exploitation has been identified at the time of analysis, though the vulnerability has been assigned ENISA EUVD ID EUVD-2026-16340 and tracked across major Linux distributions.
libsoup's SoupServer contains a use-after-free vulnerability in the soup_server_disconnect() function that prematurely frees connection objects while TLS handshakes are pending, allowing remote unauthenticated attackers to trigger a server crash via denial of service when a handshake completes after memory deallocation. The vulnerability affects Red Hat Enterprise Linux versions 6, 7, 8, 9, and 10, as well as Ubuntu and Debian distributions across multiple releases. No public exploit code or active exploitation has been confirmed at the time of analysis.
Keycloak allows authenticated administrators with manage-clients permission to escalate privileges to manage-permissions level, enabling unauthorized control over roles, users, and administrative functions within a realm. Red Hat Build of Keycloak, JBoss Enterprise Application Platform 8, and Red Hat Single Sign-On 7 are affected when admin permissions are enabled at the realm level. The vulnerability requires high-privilege authentication but carries medium CVSS severity (6.5) due to confidentiality and integrity impact without availability compromise.
Keycloak's User-Managed Access (UMA) 2.0 Protection API fails to enforce role-based access control on the permission tickets endpoint, allowing any authenticated user with a resource server client token to enumerate all permission tickets regardless of authorization level. This information disclosure vulnerability affects Red Hat Build of Keycloak across multiple versions and requires valid authentication to exploit, posing a moderate risk to multi-tenant environments where ticket enumeration could expose sensitive access control data. No public exploit code has been identified at time of analysis.
A SSRF vulnerability in A flaw (CVSS 3.1) that allows the attacker. Remediation should follow standard vulnerability management procedures.
A resource exhaustion vulnerability exists in Undertow where remote attackers can send HTTP GET requests with multipart/form-data content to trigger premature parsing and disk storage of request data, leading to Denial of Service when applications use parameter retrieval methods like getParameterMap(). The vulnerability affects multiple Red Hat products including Enterprise Linux 8, 9, and 10, JBoss Enterprise Application Platform 7 and 8, Red Hat Fuse 7, and several Apache Camel variants. An attacker with network access and no authentication can exhaust server disk resources with moderate attack complexity, causing service unavailability.
A security vulnerability in An incomplete fix for CVE-2024-47778 (CVSS 5.1) that allows an out-of-bounds read. Remediation should follow standard vulnerability management procedures.
A specially crafted XCOFF object file can trigger an out-of-bounds memory read in the GNU Binutils BFD library due to improper validation of relocation type values. This affects Red Hat Enterprise Linux versions 6 through 10 and Red Hat OpenShift Container Platform 4, potentially allowing local attackers with user interaction to crash affected tools or disclose sensitive memory contents. While not currently listed in CISA KEV as actively exploited, the vulnerability is tracked across Red Hat, Sourceware, and Bugzilla with upstream references indicating visibility and likely patch development.
Keycloak contains an information disclosure vulnerability in the identity-first login flow when Organizations are enabled, where differential error messages allow remote attackers to enumerate valid user accounts without authentication. The vulnerability affects Red Hat Build of Keycloak across multiple versions, and while the CVSS score is low (3.7), the attack requires only network access with no user interaction. This user enumeration flaw could facilitate credential stuffing, phishing, or social engineering campaigns by confirming the existence of target accounts.
Keycloak's User-Managed Access endpoint fails to properly enforce access control on PUT operations, permitting authenticated attackers to modify protected resources despite the allowRemoteResourceManagement restriction being disabled. This access control bypass affects data integrity and impacts any organization using Keycloak for identity and access management. The vulnerability requires valid credentials to exploit and currently has no available patch.
A remote code execution vulnerability in A flaw (CVSS 5.8) that allows an attacker. Remediation should follow standard vulnerability management procedures.
Unauthenticated remote attackers can exhaust memory in Red Hat Build of Keycloak 26.4 and 26.4.10 by sending highly compressed SAML requests that bypass decompression size limits, triggering denial of service. The vulnerability affects SAML Redirect Binding implementations that fail to enforce resource constraints during DEFLATE decompression, allowing attackers to crash the application with OutOfMemoryError conditions. No patch is currently available.
SQL injection in the Katello plugin for Red Hat Satellite 6 allows authenticated remote attackers to execute arbitrary SQL commands via the sort_by parameter in the /api/hosts/bootc_images endpoint. An attacker can exploit this flaw to trigger database errors causing denial of service or conduct blind SQL injection attacks to extract sensitive information from the database. No patch is currently available for this vulnerability.
HTTP/2 server implementations in libsoup across Debian and Red Hat Enterprise Linux versions contain a use-after-free vulnerability that allows unauthenticated remote attackers to trigger application crashes through specially crafted requests. Exploitation results in denial of service by forcing the application to access freed memory, causing instability. No patch is currently available for this medium-severity flaw.
A security vulnerability in A flaw (CVSS 3.9). Remediation should follow standard vulnerability management procedures.

High severity vulnerability in systemd. A flaw was found in systemd. The systemd-machined service contains an Improper Access Control vulnerability due to insufficient validation of the class parameter in the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged user can exploit this by attempting to register a machine with a specific class value, which may leave behind a usable, attacker-controlled machine object. This al...
Medium severity vulnerability in systemd. A container privilege escalation flaw was found in certain Fuse images. This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the a...
