| Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name. This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.4-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.27-S1. | ||||
| CVE-2024-45338 | 1 Redhat | 27 Acm, Advanced Cluster Security, Ceph Storage and 24 more | 2026-04-15 | 5.3 Medium |
| An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service. | ||||
| CVE-2024-23185 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 7.5 High |
| Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "full_value" buffer out of the smaller chunks. The full_value buffer has no size limit, so large headers can cause large memory usage. It doesn't matter whether it's a single long header line, or a single header split into multiple lines. This bug exists in all Dovecot versions. Incoming mails typically have some size limits set by MTA, so even largest possible header size may still fit into Dovecot's vsz_limit. So attackers probably can't DoS a victim user this way. A user could APPEND larger mails though, allowing them to DoS themselves (although maybe cause some memory issues for the backend in general). One can implement restrictions on headers on MTA component preceding Dovecot. No publicly available exploits are known. | ||||
| CVE-2025-52570 | 2026-04-15 | N/A | ||
| Letmein is an authenticating port knocker. Prior to version 10.2.1, The connection limiter is implemented incorrectly. It allows an arbitrary amount of simultaneously incoming connections (TCP, UDP and Unix socket) for the services letmeind and letmeinfwd. Therefore, the command line option num-connections is not effective and does not limit the number of simultaneously incoming connections. This issue has been patched in version 10.2.1. | ||||
| CVE-2025-14876 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-04-15 | 5.5 Medium |
| A flaw was found in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, leading to uncontrolled memory allocation. This can result in a denial of service (DoS) on the host system by causing the QEMU process to terminate unexpectedly. | ||||
| CVE-2020-37134 | 1 Ultravnc | 2 Ultravnc, Vnc Viewer | 2026-04-15 | 7.5 High |
| UltraVNC Viewer 1.2.4.0 contains a denial of service vulnerability that allows attackers to crash the application by manipulating VNC Server input. Attackers can generate a malformed 256-byte payload and paste it into the VNC Server connection dialog to trigger an application crash. | ||||
| CVE-2022-50799 | 1 Fetch Softworks | 1 Fetch Ftp Client | 2026-04-15 | 7.5 High |
| Fetch FTP Client 5.8.2 contains a denial of service vulnerability that allows attackers to trigger 100% CPU consumption by sending long server responses. Attackers can send specially crafted FTP server responses exceeding 2K bytes to cause excessive resource utilization and potentially crash the application. | ||||
| CVE-2025-37166 | 1 Hpe | 1 Aruba Instant On | 2026-04-15 | 7.5 High |
| A vulnerability affecting HPE Networking Instant On Access Points has been identified where a device processing a specially crafted packet could enter a non-responsive state, in some cases requiring a hard reset to re-establish services. A malicious actor could leverage this vulnerability to conduct a Denial-of-Service attack on a target network. | ||||
| CVE-2025-59045 | 2026-04-15 | N/A | ||
| Stalwart is a mail and collaboration server. Starting in version 0.12.0 and prior to version 0.13.3, a memory exhaustion vulnerability exists in Stalwart's CalDAV implementation that allows authenticated attackers to cause denial-of-service by triggering unbounded memory consumption through recurring event expansion. An authenticated attacker can crash the Stalwart server by creating recurring events with large payloads and triggering their expansion through CalDAV REPORT requests. A single malicious request expanding 300 events with 1000-character descriptions can consume up to 2 GB of memory. The vulnerability exists in the `ArchivedCalendarEventData.expand` function, which processes CalDAV `REPORT` requests with event expansion. When a client requests recurring events in their expanded form using the `<C:expand>` element, the server stores all expanded event instances in memory without enforcing size limits. Users should upgrade to Stalwart version 0.13.3 or later to receive a fix. If immediate upgrading is not possible, implement memory limits at the container/system level; monitor server memory usage for unusual spikes; consider rate limiting CalDAV REPORT requests; and restrict CalDAV access to trusted users only. | ||||
| CVE-2021-47894 | 1 Northwest Performance Software | 1 Managed Switch Port Mapping Tool | 2026-04-15 | 7.5 High |
| Managed Switch Port Mapping Tool 2.85.2 contains a denial of service vulnerability that allows attackers to crash the application by creating an oversized buffer. Attackers can generate a 10,000-character buffer and paste it into the IP Address and SNMP Community Name fields to trigger the application crash. | ||||
| CVE-2020-37085 | 1 Sunnysidesoft | 1 Virtualtablet Server | 2026-04-15 | 7.5 High |
| VirtualTablet Server 3.0.2 contains a denial of service vulnerability that allows attackers to crash the service by sending oversized string payloads through the Thrift protocol. Attackers can exploit the vulnerability by sending a long string to the send_say() method, causing the server to become unresponsive. | ||||
| CVE-2024-22436 | 2026-04-15 | 6.5 Medium | ||
| A security vulnerability in HPE IceWall Agent products could be exploited remotely to cause a denial of service. | ||||
| CVE-2025-31990 | 1 Hclsoftware | 1 Hcl Devops Velocity | 2026-04-15 | 6.8 Medium |
| Rate limiting for certain API calls is not being enforced, making HCL Velocity vulnerable to Denial of Service (DoS) attacks. An attacker could flood the system with a large number of requests, overwhelming its resources and causing it to become unresponsive to legitimate users. This vulnerability is fixed in 5.1.7. | ||||
| CVE-2025-9368 | 1 Rockwellautomation | 1 432es-ig3 Series A | 2026-04-15 | N/A |
| A security issue exists within 432ES-IG3 Series A, which affects GuardLink® EtherNet/IP Interface, resulting in denial-of-service. A manual power cycle is required to recover the device. | ||||
| CVE-2025-54121 | 1 Encode | 1 Starlette | 2026-04-15 | 5.3 Medium |
| Starlette is a lightweight ASGI (Asynchronous Server Gateway Interface) framework/toolkit, designed for building async web services in Python. In versions 0.47.1 and below, when parsing a multi-part form with large files (greater than the default max spool size) starlette will block the main thread to roll the file over to disk. This blocks the event thread which means the application can't accept new connections. The UploadFile code has a minor bug where instead of just checking for self._in_memory, the logic should also check if the additional bytes will cause a rollover. The vulnerability is fixed in version 0.47.2. | ||||
| CVE-2021-47876 | 1 Geogebra | 1 Classic | 2026-04-15 | 7.5 High |
| GeoGebra Classic 5.0.631.0-d contains a denial of service vulnerability in the input field that allows attackers to crash the application by sending oversized buffer content. Attackers can generate a large buffer of 800,000 repeated characters and paste it into the 'Entrada:' input field to trigger an application crash. | ||||
| CVE-2025-2813 | 1 Phoenixcontact | 2 Axl F Bk Eip, Axl F Bk Pn | 2026-04-15 | 7.5 High |
