CVE-2026-9064 1 Redhat 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more 2026-11-05 7.5 High
A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service.
CVE-2026-80110 1 Redhat 6 Certificate System, Dogtag Certificate System, Enterprise Linux and 3 more 2026-11-04 8.1 High
A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw -- intended to require Administrator-level profiles.create permission -- to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy.
CVE-2026-79678 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more 2026-11-04 8.1 High
A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.
CVE-2026-7867 1 Redhat 3 Enterprise Linux, Enterprise Linux Eus, Rhel Els 2026-11-04 7.8 High
A flaw was found in udisks2. A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This allows the attacker to spoof the 'as-user' parameter, mounting filesystems on behalf of arbitrary users, including privileged accounts. This can lead to local privilege escalation through mount point injection and manipulation of the mount namespace visible to privileged users.
CVE-2026-76578 1 Redhat 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more 2026-11-04 9.8 Critical
A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.
CVE-2026-76561 1 Redhat 9 Certificate System, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.2 High
A flaw was found in Dogtag PKI, as used by FreeIPA's certificate authority component. The certificate profile import functionality does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit Dogtag's ExternalProcessConstraint mechanism to execute arbitrary commands with attacker-controlled environment variables, achieving code execution as the pkiuser account.
CVE-2026-76560 1 Redhat 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more 2026-11-04 7.5 High
A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user.
CVE-2026-73198 2 Freeipa, Redhat 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.5 High
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.
CVE-2026-73197 2 Freeipa, Redhat 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.5 High
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.
CVE-2026-72694 2 Mrtgconfig, Redhat 9 Mrtg, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.1 High
A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files.
CVE-2026-59692 2 Gstreamer, Redhat 9 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.5 High
A stack buffer overflow vulnerability was found in GStreamer's DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.
CVE-2026-59691 2 Gstreamer, Redhat 9 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.1 High
A heap buffer overflow vulnerability was found in GStreamer's rfbsrc plugin. When a client connects to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates, the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit pixels. This type mismatch causes an out-of-bounds heap write that can lead to denial of service (process crash) and potential memory corruption.
CVE-2026-58379 2 Gimp, Redhat 7 Gimp, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-11-04 7.3 High
A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.
CVE-2026-63622 2 Libvirt, Redhat 11 Libvirt, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-11-04 7.8 High
A flaw was found in libvirt. A local attacker, specifically a process running as the confined `swtpm` user, could exploit a symlink-following vulnerability in the `virFileChownFiles()` function. By planting a symbolic link within the `swtpm` state directory, the attacker could trick the root-level libvirt daemon into changing the ownership of an arbitrary file to the `swtpm` user. This allows for privilege escalation from the `swtpm` sandbox to root-level file ownership control.
CVE-2026-5674 2 Pipewire, Redhat 6 Pipewire, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-04 8.8 High
A flaw was found in PipeWire, a multimedia server. This vulnerability allows an attacker to escape sandboxed applications, such as Flatpak, by exploiting PipeWire's PulseAudio compatibility layer. An attacker with minimal permissions within a sandboxed environment can load a malicious library, leading to arbitrary code execution outside the sandbox and potential compromise of the user's system.
CVE-2026-4111 1 Redhat 13 Ai Inference Server, Cert Manager, Discovery and 10 more 2026-11-04 7.5 High
A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives.
CVE-2026-52722 2 Gstreamer Project, Redhat 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 7.1 High
A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and leading to out-of-bounds reads. A remote attacker could trick a user into opening a specially crafted VMnc file, potentially causing a crash or information disclosure.
CVE-2026-52720 2 Gstreamer Project, Redhat 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-11-04 8.8 High
A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code execution or a crash.
CVE-2026-52719 2 Gstreamer Project, Redhat 6 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-11-04 7.1 High
An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The JPEG parser reads a segment length value from the bitstream without validating it against available data. A remote attacker could trick a user into opening a specially crafted JPEG file, causing downstream parsing to read beyond the provided input buffer, leading to a crash or potential information disclosure.
CVE-2026-50264 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-11-04 7.8 High
An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger an out-of-bounds heap write. This may be used to crash the server, or for privilege escalation if the X server runs as root.
