CVE-2026-0968 2 Libssh, Redhat 2 Libssh, Enterprise Linux 2026-05-19 N/A 3.1 LOW
A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can cause unexpected behavior or lead to a denial of service (DoS) due to application crashes.
CVE-2026-0967 2 Libssh, Redhat 2 Libssh, Enterprise Linux 2026-05-19 N/A 5.5 MEDIUM
A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client.
CVE-2026-0966 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-05-19 N/A 8.2 HIGH
A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process.
CVE-2026-0965 2 Libssh, Redhat 2 Libssh, Enterprise Linux 2026-05-19 N/A 3.3 LOW
A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by causing the system to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations.
CVE-2026-0964 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-05-19 N/A 6.3 MEDIUM
A malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This is the same issue as in OpenSSH, tracked as CVE-2019-6111.
CVE-2025-5351 2 Libssh, Redhat 3 Libssh, Enterprise Linux, Openshift Container Platform 2026-05-19 N/A 6.5 MEDIUM
A flaw was found in the key export functionality of libssh. The issue occurs in the internal function responsible for converting cryptographic keys into serialized formats. During error handling, a memory structure is freed but not cleared, leading to a potential double free issue if an additional failure occurs later in the function. This condition may result in heap corruption or application instability in low-memory scenarios, posing a risk to system reliability where key export operations are performed.
CVE-2026-7163 1 Redhat 1 Multicluster Engine For Kubernetes 2026-05-19 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-2025-23368 1 Redhat 3 Data Grid, Jboss Enterprise Application Platform, Wildfly Core 2026-05-18 N/A 8.1 HIGH
A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI.
CVE-2026-4948 2 Firewalld, Redhat 2 Firewalld, Enterprise Linux 2026-05-15 N/A 5.5 MEDIUM
A flaw was found in firewalld. A local unprivileged user can exploit this vulnerability by mis-authorizing two runtime D-Bus (Desktop Bus) setters, setZoneSettings2 and setPolicySettings. This mis-authorization allows the user to modify the runtime firewall state without proper authentication, leading to unauthorized changes in network security configurations.
CVE-2026-6732 2 Redhat, Xmlsoft 5 Enterprise Linux, Hardened Images, Jboss Core Services and 2 more 2026-05-15 N/A 6.5 MEDIUM
A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type confusion error that causes the application to crash. This results in a denial of service (DoS), making the affected system or application unavailable.
CVE-2012-4550 1 Redhat 1 Jboss Enterprise Application Platform 2026-05-14 6.4 MEDIUM 5.3 MEDIUM
A flaw was found in JBoss Enterprise Application Platform. When role-based authorization is used for Enterprise Java Beans (EJB) access, the system does not correctly call the necessary authorization modules. This prevents Java Authorization Contract for Containers (JACC) permissions from being applied, allowing remote attackers to gain unauthorized access to EJBs.
CVE-2012-4549 1 Redhat 1 Jboss Enterprise Application Platform 2026-05-14 5.8 MEDIUM 6.5 MEDIUM
A flaw was found in JBoss Enterprise Application Platform. The `processInvocation` function within the `org.jboss.as.ejb3.security.AuthorizationInterceptor` component incorrectly authorizes all requests when no roles are defined for an Enterprise Java Beans (EJB) method invocation. This allows attackers to bypass intended access restrictions for EJB methods, leading to unauthorized access to sensitive functionalities.
CVE-2017-1000116 3 Debian, Mercurial, Redhat 8 Debian Linux, Mercurial, Enterprise Linux Desktop and 5 more 2026-05-13 10.0 HIGH 9.8 CRITICAL
Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.
CVE-2017-11213 6 Adobe, Apple, Google and 3 more 10 Flash Player, Macos, Chrome Os and 7 more 2026-05-13 10.0 HIGH 9.8 CRITICAL
An issue was discovered in Adobe Flash Player 27.0.0.183 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer due to an integer overflow; the computation is part of the abstraction that creates an arbitrarily sized transparent or opaque bitmap image. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.
CVE-2017-12629 4 Apache, Canonical, Debian and 1 more 5 Solr, Ubuntu Linux, Debian Linux and 2 more 2026-05-13 7.5 HIGH 9.8 CRITICAL
Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.
CVE-2017-5042 6 Apple, Debian, Google and 3 more 9 Macos, Debian Linux, Android and 6 more 2026-05-13 3.3 LOW 5.7 MEDIUM
Cast in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android sent cookies to sites discovered via SSDP, which allowed an attacker on the local network segment to initiate connections to arbitrary URLs and observe any plaintext cookies sent.
CVE-2015-7703 5 Debian, Netapp, Ntp and 2 more 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more 2026-05-13 4.3 MEDIUM 7.5 HIGH
The "pidfile" or "driftfile" directives in NTP ntpd 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77, when ntpd is configured to allow remote configuration, allows remote attackers with an IP address that is allowed to send configuration requests, and with knowledge of the remote configuration password to write to arbitrary files via the :config command.
CVE-2017-14746 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2026-05-13 7.5 HIGH 9.8 CRITICAL
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.
CVE-2017-13086 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2026-05-13 5.4 MEDIUM 6.8 MEDIUM
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
CVE-2017-5093 6 Apple, Debian, Google and 3 more 9 Macos, Debian Linux, Android and 6 more 2026-05-13 4.3 MEDIUM 6.5 MEDIUM
Inappropriate implementation in modal dialog handling in Blink in Google Chrome prior to 60.0.3112.78 for Mac, Windows, Linux, and Android allowed a remote attacker to prevent a full screen warning from being displayed via a crafted HTML page.
