A flaw was found in Bombastic, which allows authenticated users to upload compressed (bzip2 or zstd) SBOMs. The API endpoint verifies the presence of some fields and values in the JSON. To perform this verification, the uploaded file must first be decompressed.

Rubygems.org is the Ruby community's gem hosting service. A Gem publisher can cause a Remote DoS when publishing a Gem. This is due to how Ruby reads the Manifest of Gem files when using Gem::Specification.from_yaml. from_yaml makes use of SafeYAML.load which allows YAML aliases inside the YAML-based metadata of a gem. YAML aliases allow for Denial of Service attacks with so-called `YAML-bombs` (comparable to Billion laughs attacks). This was patched. There is is no action required by users. This issue is also tracked as GHSL-2024-001 and was discovered by the GitHub security lab.

An issue was discovered in OpenDDS commit b1c534032bb62ad4ae32609778de6b8d6c823a66, allows a local attacker to cause a denial of service and obtain sensitive information via the max_samples parameter within the DataReaderQoS component.

A vulnerability was found in yarnpkg Yarn up to 1.22.22. It has been classified as problematic.

PingCAP TiDB v8.1.0 was discovered to contain a buffer overflow via the component (*Column).GetDecimal. This allows attackers to cause a Denial of Service (DoS) via a crafted input to the 'RemoveUnnecessaryFirstRow', it will check the expression between 'Agg' and 'GroupBy', but does not check the return type. NOTE: PingCAP disputes this, arguing that reproduction did not cause the security impact of service interruption to other users. They maintain it is a complex query bug in the product but not a DoS.

In Splunk Enterprise Security (ES) versions below 7.1.2, an attacker can use investigation attachments to perform a denial of service (DoS) to the Investigation. The attachment endpoint does not properly limit the size of the request which lets an attacker cause the Investigation to become inaccessible.

Discourse is a platform for community discussion. For fields that are client editable, limits on sizes are not imposed. This allows a malicious actor to cause a Discourse instance to use excessive disk space and also often excessive bandwidth. The issue is patched 3.1.4 and 3.2.0.beta4.

discourse-calendar is a discourse plugin which adds the ability to create a dynamic calendar in the first post of a topic. The limit on region value length is too generous.

An infinite loop in the retrieveActiveBody function of Soot before v4.4.1 under Java 8 allows attackers to cause a Denial of Service (DoS).

Nextcloud calendar is a calendar app for the Nextcloud server platform. Due to missing precondition checks the server was trying to validate strings of any length as email addresses even when megabytes of data were provided, eventually making the server busy and unresponsive. It is recommended that the Nextcloud Calendar app is upgraded to 4.4.4. The only workaround for users unable to upgrade is to disable the calendar app.

An issue was discovered in MB CONNECT LINE mymbCONNECT24 and mbCONNECT24 through 2.6.2. There is an unused function that allows an authenticated attacker to use up all available IPs of an account and thus not allow creation of new devices and users.

Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.

A DOS vulnerability exists in Gitlab CE/EE >=10.3, <13.4.7,>=13.5, <13.5.5,>=13.6, <13.6.2 that allows an attacker to trigger uncontrolled resource by bypassing input validation in markdown fields.

Uncontrolled resource consumption in Mattermost version 6.6.0 and earlier allows an authenticated attacker to crash the server via a crafted SVG attachment on a post.

A flaw was found in the Hive hibernation controller component of OpenShift Dedicated. The ClusterDeployment.hive.openshift.io/v1 resource can be created with the spec.installed field set to true, regardless of the installation status, and a positive timespan for the spec.hibernateAfter value. If a ClusterSync.hiveinternal.openshift.io/v1alpha1 resource is also created, the hive hibernation controller will enter the reconciliation loop leading to a panic when accessing a non-existing field in the ClusterDeployment’s status section, resulting in a denial of service.

When adding an external mail account, processing of IMAP "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue IMAP service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted IMAP server response to reasonable length/size. No publicly available exploits are known.

When adding an external mail account, processing of POP3 "capabilities" responses are not limited to plausible sizes. Attacker with access to a rogue POP3 service could trigger requests that lead to excessive resource usage and eventually service unavailability. We now limit accepted POP3 server response to reasonable length/size. No publicly available exploits are known.

The Mojolicious module before 9.11 for Perl has a bug in format detection that can potentially be exploited for denial of service.

Discourse is an open source discussion platform. Prior to version 3.0.6 of the `stable` branch and version 3.1.0.beta7 of the `beta` and `tests-passed` branches, a malicious user can prevent the defer queue from proceeding promptly on sites hosted in the same multisite installation. The issue is patched in version 3.0.6 of the `stable` branch and version 3.1.0.beta7 of the `beta` and `tests-passed` branches. There are no known workarounds for this vulnerability. Users of multisite configurations should upgrade.

Discourse is an open-source discussion platform. Prior to version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches, when submitting a membership request, there is no character limit for the reason provided with the request. This could potentially allow a user to flood the database with a large amount of data. However it is unlikely this could be used as part of a DoS attack, as the paths reading back the reasons are only available to administrators. Starting in version 3.0.1 on the `stable` branch and 3.1.0.beta2 on the `beta` and `tests-passed` branches, a limit of 280 characters has been introduced for membership requests.
