Vulnerability from github – Published: 2026-02-13 12:31 – Updated: 2026-03-23 21:30A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component.

Vulnerability from github – Published: 2026-07-21 21:32 – Updated: 2026-07-22 21:31Data::RadixTree::Shared versions before 0.02 for Perl allow an out-of-bounds read via unvalidated node and arena indices in rdx_find_locked.
The attach-time validator rdx_validate_header checks the header scalars and region layout against the file size, but does not validate the node records it then trusts. rdx_find_locked indexes nodes[cur].children[k] and reads each node's label_off and label_len raw from the mmap'd segment, none bounded against the node count or the arena size.
A local peer that can write the backing file can leave the header valid while poisoning the node records, so a lookup dereferences an out-of-bounds node or arena index, reading adjacent memory or crashing the process.

GHSA-HG6H-53HM-4646
Vulnerability from github – Published: 2025-12-18 21:31 – Updated: 2025-12-19 18:31A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association, a PFCP Session Establishment Request that includes a CreateFAR with an empty or truncated IPv4 address field is not properly validated. During parsing, parseFAR() calls ip2int(), which performs an out-of-bounds read on the IPv4 address buffer and triggers an index-out-of-range panic. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.

GHSA-HGHW-P2MW-FVCH
Vulnerability from github – Published: 2026-06-15 21:30 – Updated: 2026-07-08 15:31A vulnerability was found in the GStreamer RealMedia demuxer (gst-plugins-ugly). When processing a RealMedia (.rm) file, the demuxer parses MDPR (media properties) chunks to configure audio streams. For audio stream header versions 4 and 5, the parser reads fields such as codec type, packet size, sample rate, channel count, and extra codec data length from fixed offsets within the chunk without first checking that the chunk contains enough data. If a malicious file provides an MDPR chunk that is too small to contain a complete audio stream header, the parser reads beyond the end of the buffer. This can cause the application to crash. In some cases, bytes read past the buffer boundary may be incorporated into stream metadata, which could result in limited information disclosure.

Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Strategy: Language Selection
Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
