CVE-2025-5914 2 Libarchive, Redhat 3 Libarchive, Enterprise Linux, Openshift Container Platform 2026-08-02 N/A 7.8 HIGH
A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
CVE-2026-2100 2 P11-kit Project, Redhat 3 P11-kit, Enterprise Linux, Hardened Images 2026-08-02 N/A 5.3 MEDIUM
A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.
CVE-2026-4878 2 Libcap Project, Redhat 3 Libcap, Enterprise Linux, Openshift Container Platform 2026-08-02 N/A 6.7 MEDIUM
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
CVE-2025-5318 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Openshift Container Platform 2026-08-02 N/A 8.1 HIGH
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
CVE-2026-46579 1 Redhat 2 Openshift Container Platform, Openshift Router 2026-08-02 N/A 7.4 HIGH
A flaw was found in the OpenShift Router. When a Route has `insecureEdgeTerminationPolicy` set to Allow, the HTTP frontend does not remove `X-SSL-Client-*` headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted `X-SSL-Client-*` headers. As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.
CVE-2026-1784 1 Redhat 1 Openshift Container Platform 2026-08-02 N/A 8.8 HIGH
The Route OpenShift resource allows to define routes to make pods reachable at a subdomain through HAProxy. It was found that the checks performed on the spec.path YAML stanza in a Route document was insufficient and could allow a controlled injection of the HAProxy configuration.
CVE-2026-7163 1 Redhat 1 Multicluster Engine For Kubernetes 2026-08-01 N/A 6.1 MEDIUM
A vulnerability in the assisted-service REST API, an optional Assisted Installer (assisted-service) component in the Multicluster Engine (MCE), allows an authenticated user with minimal namespace-scoped privileges to obtain administrative credentials for arbitrary clusters provisioned through the hub. The credentials download endpoint (GET /v2/clusters/{cluster_id}/credentials, which returns the kubeadmin password) and the kubeconfig download endpoint are operational in AUTH_TYPE=local mode, the only authentication mode available in on-premises ACM/MCE hub deployments. The local authenticator unconditionally grants full administrative access to any request bearing a valid JWT, with no per-endpoint restrictions. A valid local JWT is embedded as a plaintext query parameter in InfraEnvStatus.ISODownloadURL and is readable by any user who has get rights on an InfraEnv object in their own namespace. The affected components ship as part of Multicluster Engine (MCE). The Red Hat Advanced Cluster Management (ACM) deployments that include MCE are equally affected. This issue does not affect the hosted SaaS offering (console.redhat.com), which uses a different authentication mode. Successful exploitation gives the attacker the kubeadmin password and kubeconfig for any OpenShift cluster provisioned through the affected hub, granting unrestricted root-level administrative access to those spoke clusters.
CVE-2021-40438 11 Apache, Broadcom, Debian and 8 more 40 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 37 more 2026-08-01 6.8 MEDIUM 9.0 CRITICAL
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2017-12615 4 Apache, Microsoft, Netapp and 1 more 23 Tomcat, Windows, 7-mode Transition Tool and 20 more 2026-08-01 6.8 MEDIUM 8.1 HIGH
When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.
CVE-2026-48864 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-31 N/A 7.8 HIGH
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
CVE-2026-9150 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-31 N/A 6.5 MEDIUM
A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
CVE-2026-9149 2 Opensuse, Redhat 6 Libsolv, Enterprise Linux, Hardened Images and 3 more 2026-07-31 N/A 6.5 MEDIUM
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
CVE-2026-59849 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 3.1 LOW
A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service.
CVE-2026-59850 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 4.3 MEDIUM
A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.
CVE-2026-59851 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 8.8 HIGH
A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users.
CVE-2026-15370 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 6.7 MEDIUM
A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can overflow that stack buffer and may lead to crashes or possible code execution on the server.
CVE-2026-59843 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 6.5 MEDIUM
A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service.
CVE-2026-59842 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 3.7 LOW
A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory.
CVE-2026-59844 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 6.5 MEDIUM
A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests.
CVE-2026-59845 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Hardened Images 2026-07-30 N/A 5.3 MEDIUM
A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service.
