CVSS v3.1 |
| A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack.
This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0 through 9.19.24, and 9.18.11-S1 through 9.18.27-S1. |
| rplay through 3.3.2 allows attackers to cause a denial of service (SIGSEGV and daemon crash) or possibly have unspecified other impact. This occurs in memcpy in the RPLAY_DATA case in rplay_unpack in librplay/rplay.c, potentially reachable via packet data with no authentication. |
| Improper resource management in firmware of some Solidigm DC Products may allow an attacker to potentially enable denial of service. |
| 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. |
| Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. Prior to versions 3.3.0 and 2.19.4, an attacker could present an ECDSA X.509 certificate using explicit encoding where the parameters are very large. The proof of concept used a 16Kbit prime for this purpose. When parsing, the parameter is checked to be prime, causing excessive computation. This was patched in 2.19.4 and 3.3.0 to allow the prime parameter of the elliptic curve to be at most 521 bits. No known workarounds are available. Note that support for explicit encoding of elliptic curve parameters is deprecated in Botan. |
| An unauthenticated remote attacker can cause a DoS in the controller due to uncontrolled resource consumption. |
| 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. |
| tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations. |
| IBM Db2 Big SQL on Cloud Pak for Data versions 7.6 (on CP4D 4.8), 7.7 (on CP4D 5.0), and 7.8 (on CP4D 5.1) do not properly limit the allocation of system resources. An authenticated user with internal knowledge of the environment could exploit this weakness to cause a denial of service. |
| Varnish Cache before 7.3.2 and 7.4.x before 7.4.3 (and before 6.0.13 LTS), and Varnish Enterprise 6 before 6.0.12r6, allows credits exhaustion for an HTTP/2 connection control flow window, aka a Broke Window Attack. |
| 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. |
| Bugsink is a self-hosted error tracking tool. In versions prior to 2.0.5, brotli "bombs" (highly compressed brotli streams, such as many zeros) can be sent to the server. Since the server will attempt to decompress these streams before applying various maximums, this can lead to exhaustion of the available memory and thus a Denial of Service. This can be done if the `DSN` is known, which it is in many common setups (JavaScript, Mobile Apps). The issue is patched in Bugsink version `2.0.5`. The vulnerability is similar to, but distinct from, another brotli-related problem in Bugsink, GHSA-rrx3-2x4g-mq2h/CVE-2025-64509. |
| Aerohive HiveOS contains a denial of service vulnerability in the NetConfig UI that allows unauthenticated attackers to render the web interface unusable. Attackers can send a crafted HTTP request to the action.php5 script with specific parameters to trigger a 5-minute service disruption. |
| Starlette is an Asynchronous Server Gateway Interface (ASGI) framework/toolkit. Prior to version 0.40.0, Starlette treats `multipart/form-data` parts without a `filename` as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload arbitrary large form fields and cause Starlette to both slow down significantly due to excessive memory allocations and copy operations, and also consume more and more memory until the server starts swapping and grinds to a halt, or the OS terminates the server process with an OOM error. Uploading multiple such requests in parallel may be enough to render a service practically unusable, even if reasonable request size limits are enforced by a reverse proxy in front of Starlette. This Denial of service (DoS) vulnerability affects all applications built with Starlette (or FastAPI) accepting form requests. Verison 0.40.0 fixes this issue. |
| Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors sending emails to a victim, this is a security issue. An external attacker can send specially crafted messages that consume target system resources and cause outage. One can implement restrictions on address headers on MTA component preceding Dovecot. No publicly available exploits are known. |
| 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. |
| gorilla/schema converts structs to and from form values. Prior to version 1.4.1 Running `schema.Decoder.Decode()` on a struct that has a field of type `[]struct{...}` opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of `schema.Decoder.Decode()` on a struct with arrays of other structs could be vulnerable to this memory exhaustion vulnerability. Version 1.4.1 contains a patch for the issue. |
| An e-mail flooding vulnerability in StrangeBee TheHive 5.2.0 before 5.2.16, 5.3.0 before 5.3.11, 5.4.0 before 5.4.10, and 5.5.0 before 5.5.1 allows unauthenticated remote attackers to use the password reset feature without limits. This can lead to several consequences, including mailbox storage exhaustion for targeted users, reputation damage to the SMTP server, potentially causing it to be blacklisted, and overload of the SMTP server's outbound mail queue. |
| 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. |
| Allocation of resources without limits or throttling issue exists in HMI ViewJet C-more series and HMI GC-A2 series, which may allow a remote unauthenticated attacker to cause a denial-of-service (DoS) condition. |
