GHSA-fh5r-crhr-qrrq: Apache CXF: Denial of Service vulnerability with temporary files

A potential denial of service vulnerability is present in versions of Apache CXF before 3.5.10, 3.6.5 and 4.0.6. In some edge cases, the CachedOutputStream instances may not be closed and, if backed by temporary files, may fill up the file system (it applies to servers and clients).

Traffic Alert and Collision Avoidance System (TCAS) II

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 7.1 ATTENTION: Exploitable from adjacent network Standard: Traffic Alert and Collision Avoidance System (TCAS) II Equipment: Collision Avoidance Systems Vulnerabilities: Reliance on Untrusted Inputs in a Security Decision, External Control of System or Configuration Setting 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to manipulate safety systems and cause a denial-of-service condition. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following revisions of TCAS II are affected: TCAS II: Versions 7.1 and prior 3.2 Vulnerability Overview 3.2.1 Reliance on Untrusted Inputs in a Security Decision CWE-807 By utilizing software-defined radios and a custom low-latency processing pipeline, RF signals with spoofed location data can be transmitted to aircraft targets. This can lead to the appearance of fake aircraft on displays and potentially trigger undesired Resolution Advisories (RAs). CWE-2024-9310 has been...

GHSA-gp86-q8hg-fpxj: matrix-media-repo (MMR) allows a denial of service through memory exhaustion

### Impact MMR makes requests to other servers as part of normal operation, and these resource owners can return large amounts of JSON back to MMR for parsing. In parsing, MMR can consume large amounts of memory and exhaust available memory. ### Patches This is fixed in [MMR v1.3.8](https://github.com/t2bot/matrix-media-repo/releases/tag/v1.3.8). ### Workarounds Forward proxies can be configured to block requests to unsafe hosts. Alternatively, MMR processes can be configured with memory limits and auto-restart. Running multiple MMR processes concurrently can help ensure a restart does not overly impact users.

GHSA-vc2m-hw89-qjxf: matrix-media-repo (MMR) allows denial of service/high operating costs through unauthenticated downloads

### Impact 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. ### Patches 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 impleme...

GHSA-p9v8-q5m4-pf46: CVE-2024-5138: snapd snapctl auth bypass

### Impact A snap with prior permissions to create a mount entry on the host, such as firefox, normally uses the permission from one of the per-snap hook programs. A unprivileged users cannot normally trigger that behaviour by using `snap run --shell firefox` followed by `snapctl mount`, since snapd validates the requesting user identity (root or non-root). The issue allows unprivileged users to bypass that check by crafting a malicious command line vector which confuses snapd into thinking the help message is requested. Unprivileged user on a default installation of Ubuntu, where firefox is as provided as a snap, may cause a denial-of-service attack by repeatedly mounting hunspell database over and over and eventually exhausting system memory. Other attacks, reliant on the same underying mechanism (mount), are possible. In all cases the snap must be installed and grated permission to perform this action (by connecting an appropriate snap interface), which requires administrative pr...

GHSA-6fx8-h7jm-663j: parse-uri Regular expression Denial of Service (ReDoS)

An issue in parse-uri v1.0.9 allows attackers to cause a Regular expression Denial of Service (ReDoS) via a crafted URL.

GHSA-qcgg-j2x8-h9g8: Django has a potential denial-of-service vulnerability in IPv6 validation

An issue was discovered in Django 5.1 before 5.1.5, 5.0 before 5.0.11, and 4.2 before 4.2.18. Lack of upper-bound limit enforcement in strings passed when performing IPv6 validation could lead to a potential denial-of-service attack. The undocumented and private functions `clean_ipv6_address` and `is_valid_ipv6_address` are vulnerable, as is the `django.forms.GenericIPAddressField` form field. (The django.db.models.GenericIPAddressField model field is not affected.)

GHSA-w8xv-rwgf-4fwh: CVE-2025-0343: Swift ASN.1 can crash when parsing maliciously formed BER/DER

Swift ASN.1 can be caused to crash when parsing certain BER/DER constructions. This crash is caused by a confusion in the ASN.1 library itself which assumes that certain objects can only be provided in either constructed or primitive forms, and will trigger a `preconditionFailure` if that constraint isn't met. Importantly, these constraints are actually required to be true in DER, but that correctness wasn't enforced on the early node parser side so it was incorrect to rely on it later on in decoding, which is what the library did. These crashes can be triggered when parsing any DER/BER format object. There is no memory-safety issue here: the crash is a graceful one from the Swift runtime. The impact of this is that it can be used as a denial-of-service vector when parsing BER/DER data from unknown sources, e.g. when parsing TLS certificates. Many thanks to @baarde for reporting this issue and providing the fix.
