| CVE-2024-4140 | 2 Fedoraproject, Rjbs | 2 Fedora, Email-mime | 2025-08-26 | 7.5 High |
| An excessive memory use issue (CWE-770) exists in Email-MIME, before version 1.954, which can cause denial of service when parsing multipart MIME messages. The patch set (from 2020 and 2024) limits excessive depth and the total number of parts. | ||||
| CVE-2024-52797 | 2 Apereo, Opencast | 2 Opencast, Opencast | 2025-08-26 | 6.5 Medium |
| Opencast is free and open source software for automated video capture and distribution. First noticed in Opencast 13 and 14, Opencast's Elasticsearch integration may generate syntactically invalid Elasticsearch queries in relation to previously acceptable search queries. From Opencast version 11.4 and newer, Elasticsearch queries are retried a configurable number of times in the case of error to handle temporary losses of connection to Elasticsearch. These invalid queries would fail, causing the retry mechanism to begin requerying with the same syntactically invalid query immediately, in an infinite loop. This causes a massive increase in log size which can in some cases cause a denial of service due to disk exhaustion. Opencast 13.10 and Opencast 14.3 contain patches which address the base issue, with Opencast 16.7 containing changes which harmonize the search behaviour between the admin UI and external API. Users are strongly recommended to upgrade as soon as possible if running versions prior to 13.10 or 14.3. While the relevant endpoints require (by default) `ROLE_ADMIN` or `ROLE_API_SERIES_VIEW`, the problem queries are otherwise innocuous. This issue could be easily triggered by normal administrative work on an affected Opencast system. Those who run a version newer than 13.10 and 14.3 and see different results when searching in their admin UI vs your external API or LMS, may resolve the issue by upgrading to 16.7. No known workarounds for the vulnerability are available. | ||||
| CVE-2024-37302 | 2 Element-hq, Matrix | 2 Synapse, Synapse | 2025-08-26 | 7.5 High |
| Synapse is an open-source Matrix homeserver. Synapse versions before 1.106 are vulnerable to a disk fill attack, where an unauthenticated adversary can induce Synapse to download and cache large amounts of remote media. The default rate limit strategy is insufficient to mitigate this. This can lead to a denial of service, ranging from further media uploads/downloads failing to completely unavailability of the Synapse process, depending on how Synapse was deployed. Synapse 1.106 introduces a new "leaky bucket" rate limit on remote media downloads to reduce the amount of data a user can request at a time. This does not fully address the issue, but does limit an unauthenticated user's ability to request large amounts of data to be cached. | ||||
| CVE-2024-52805 | 2 Element-hq, Matrix | 2 Synapse, Synapse | 2025-08-26 | 7.5 High |
| Synapse is an open-source Matrix homeserver. In Synapse before 1.120.1, multipart/form-data requests can in certain configurations transiently increase memory consumption beyond expected levels while processing the request, which can be used to amplify denial of service attacks. Synapse 1.120.1 resolves the issue by denying requests with unsupported multipart/form-data content type. | ||||
| CVE-2025-3050 | 1 Ibm | 1 Db2 | 2025-08-26 | 5.3 Medium |
| IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.1 could allow an authenticated user to cause a denial of service when using Q replication due to the improper allocation of CPU resources. | ||||
| CVE-2025-54879 | 1 Joinmastodon | 1 Mastodon | 2025-08-26 | 5.3 Medium |
| Mastodon is a free, open-source social network server based on ActivityPub Mastodon which facilitates LDAP configuration for authentication. In versions 3.1.5 through 4.2.24, 4.3.0 through 4.3.11 and 4.4.0 through 4.4.3, Mastodon's rate-limiting system has a critical configuration error where the email-based throttle for confirmation emails incorrectly checks the password reset path instead of the confirmation path, effectively disabling per-email limits for confirmation requests. This allows attackers to bypass rate limits by rotating IP addresses and send unlimited confirmation emails to any email address, as only a weak IP-based throttle (25 requests per 5 minutes) remains active. The vulnerability enables denial-of-service attacks that can overwhelm mail queues and facilitate user harassment through confirmation email spam. This is fixed in versions 4.2.24, 4.3.11 and 4.4.3. | ||||
| CVE-2025-32374 | 1 Dnnsoftware | 1 Dotnetnuke | 2025-08-26 | 5.9 Medium |
| DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Possible denial of service with specially crafted information in the public registration form. This vulnerability is fixed in 9.13.8. | ||||

| IBM Cognos Analytics 11.2.0, 11.2.1, 11.2.2, 11.2.3, 11.2.4, 12.0.0, 12.0.1, 12.0.2, 12.0.3, and 12.0.4 could allow an authenticated user to cause a denial of service by sending a specially crafted request that would exhaust memory resources. | ||||
| CVE-2025-3221 | 3 Ibm, Linux, Microsoft | 4 Aix, Infosphere Information Server, Linux Kernel and 1 more | 2025-08-24 | 7.5 High |
| IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 could allow a remote attacker to cause a denial of service due to insufficient validation of incoming request resources. | ||||
| CVE-2025-43752 | 1 Liferay | 2 Dxp, Portal | 2025-08-23 | N/A |
| Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.4, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.15 and 7.4 GA through update 92 allow users to upload an unlimited amount of files through the object entries attachment fields, the files are stored in the document_library allowing an attacker to cause a potential DDoS. | ||||
| CVE-2025-55199 | 1 Helm | 1 Helm | 2025-08-21 | 6.5 Medium |
| Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero. | ||||

| CVE-2024-36403 | 1 T2bot | 1 Matrix-media-repo | 2025-08-20 | 5.3 Medium |
| Matrix Media Repo (MMR) is a highly configurable multi-homeserver media repository for Matrix. MMR before version 1.3.5 is vulnerable to unbounded disk consumption, where an unauthenticated adversary can induce it to download and cache large amounts of remote media files. MMR's typical operating environment uses S3-like storage as a backend, with file-backed store as an alternative option. Instances using a file-backed store or those which self-host an S3 storage system are therefore vulnerable to a disk fill attack. Once the disk is full, authenticated users will be unable to upload new media, resulting in denial of service. For instances configured to use a cloud-based S3 storage option, this could result in high service fees instead of a denial of service. MMR 1.3.5 introduces a new default-on "leaky bucket" rate limit to reduce the amount of data a user can request at a time. This does not fully address the issue, but does limit an unauthenticated user's ability to request large amounts of data. Operators should note that the leaky bucket implementation introduced in MMR 1.3.5 requires the IP address associated with the request to be forwarded, to avoid mistakenly applying the rate limit to the reverse proxy instead. To avoid this issue, the reverse proxy should populate the X-Forwarded-For header when sending the request to MMR. Operators who cannot update may wish to lower the maximum file size they allow and implement harsh rate limits, though this can still lead to a large amount of data to be downloaded. | ||||
