Red Hat Enterprise Linux 8: Incorrect Use of Privileged APIs
A flaw was found in Ghostscript as shipped with Red Hat Enterprise Linux 8. The correction for CVE-2019-14869 was omitted during the rebase from version 9.25 to 9.27, leaving privileged .forceput operations in the .charkeys procedure insufficiently protected.
- 7.8 High severity
Red Hat Enterprise Linux 9: Use After Free
A flaw was found in GIMP. Opening a crafted XCF that selects a path and then fails to load that path can cause a use-after-free in the main process, leading to a crash and potentially arbitrary code execution.
- 7.8 High severity
Red Hat Enterprise Linux 9: Use After Free
A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a cr
- 7.8 High severity
Red Hat Enterprise Linux 8: Stack-based Buffer Overflow
A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail can cause a heap out-of-bounds read and write in the

Red Hat Enterprise Linux 9: Out-of-bounds Read
A flaw was found in GIMP. Opening a crafted XCF with a malformed text-layer parasite can cause a heap out-of-bounds read, disclosing adjacent heap data into layer text and causing denial of service.
- 7.4 High severity
Red Hat Advanced Cluster Security for…: Authentication Bypass by Capture-replay
A flaw was found in Red Hat Advanced Cluster Security for Kubernetes (RHACS). The Central SAML authentication ACS endpoint does not retain used SAML assertion or response identifiers to prevent replay. An attacker who obtains a valid, unexpired signed SAML res

Red Hat Enterprise Linux 10: Integer Overflow or Wraparound
A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based
- 7.5 High severity
Red Hat Enterprise Linux 6: Out-of-bounds Write
A flaw was found in spice-server. Multiple migration data handlers use client-supplied offsets from SPICE_MSGC_MIGRATE_DATA messages without bounds validation, allowing a malicious authenticated SPICE client during VM live migration to read arbitrary heap memo

A flaw was found in DPDK lib/vhost. A TOCTOU double-fetch of control-queue descriptors allows a heap buffer overflow with attacker-controlled content in the VDUSE control-queue handler.
- 8.6 High severity
Red Hat Enterprise Linux 10: Out-of-bounds Write
A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can und

Red Hat OpenShift Container Platform 4.19: Execution with Unnecessary Privileges
The insights-runtime-extractor runs as a privileged DaemonSet (`hostPID: true`) that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. **fork()s** a child process 2. **setns()** into the target container's PID
- 7.8 High severity
Red Hat Hardened Images: Improper Link Resolution Before File Access
A flaw was found in BusyBox's dpkg-deb archive extraction. The ar archive handler flushes deferred symlinks after each archive member, unlike the tar, cpio, and unzip handlers which flush once after the last member. A specially crafted .deb archive with two da
- 7.2 High severity
Red Hat Hardened Images: Inconsistent Interpretation of HTTP Requests
A flaw was found in BusyBox httpd's reverse proxy feature. When the proxy is configured to forward requests matching a URL prefix to a backend server, only the first HTTP request on a TCP connection has its path rewritten. An attacker can send a pipelined seco
- 8.4 High severity
Red Hat Enterprise Linux 10: Out-of-bounds Write
A flaw was found in gst-plugins-base. A heap buffer overflow can be triggered when processing video buffers whose attached GstVideoMeta metadata declares plane strides and offsets that exceed the actual backing memory allocation. The metadata is not range-chec
- 7.5 High severity
Red Hat Enterprise Linux 9: Loop with Unreachable Exit Condition
A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS I/O handlers, retryable GnuTLS results (GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED) are handled with an unbounded busy loop instead of yielding to the event loop. A re

- 7.7 High severity
Red Hat OpenShift Container Platform 4.12: Server-Side Request Forgery
A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetc
- 7.8 High severity
Red Hat Enterprise Linux 10: Use After Free
A use-after-free flaw was found in mutter in the Wayland color-management ICC image-description path. A local attacker who can run a malicious Wayland client can destroy a wp_image_description_v1 resource while an asynchronous ICC file read is still in progres
- 8.8 High severity
ManageIQ: Deserialization of Untrusted Data
A deserialization of untrusted data vulnerability was found in ManageIQ. The YamlLoadAliases module overrides YAML.safe_load to silently fall back to YAML.unsafe_load in production when a Psych::DisallowedClass error occurs. An authenticated attacker with dial

A flaw was found in ansible-core. When installing a collection with `ansible-galaxy collection install`, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and
- 7.7 High severity
Red Hat OpenShift Container Platform 4.12: Improper Privilege Management
The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster. Ref: https://git
- 7.5 High severity
Red Hat Enterprise Linux 10: Heap-based Buffer Overflow
A heap-based buffer overflow flaw was found in Cyrus SASL. The add_to_challenge() function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size whe

Red Hat Satellite 6.16 for RHEL 8: Incorrect Authorization
A flaw was found in Candlepin. The central authorization filter incorrectly grants access when any one of multiple @Verify-annotated parameters is accessible, instead of requiring access to every verified entity. A low-privilege authenticated attacker who can

Red Hat Enterprise Linux 9: Improper Restriction of Operations within the Bounds of a Memory Buffer
A heap-based buffer overflow was found in GIMP’s DirectDraw Surface (DDS) loader. When loading a crafted DDS image, buffer sizes derived from width, height, and pitch can be computed using 32-bit arithmetic that overflows. The allocated buffer is too small for

Red Hat Enterprise Linux 10: Comparison Using Wrong Factors
A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same
- 7.1 High severity
Multicluster Global Hub: Active Debug Code
A flaw was found in postgres-exporter. Due to the blank import of `net/http/pprof`, debug endpoints are exposed on the unauthenticated metrics listener. A remote attacker within the cluster network can access these endpoints. This allows for information disclo
