Descrição técnica

ConnectBot SSH Client Library is written in Kotlin with Kaitai Struct and KStateMachine. Prior to 0.3.1, the SSH protocol parser trusts attacker-controlled inner byte lengths and element counts without verifying that they fit in the containing packet. A malicious or compromised SSH server can return a small malformed packet whose oversized declarations cause the Kaitai Struct Java runtime to attempt excessive allocation or repeated parsing before detecting truncated input. The general transport path requires a client connection but no authentication or optional feature; malformed SSH-agent messages additionally require SSH agent forwarding. The issue can raise an uncaught OutOfMemoryError and terminate the application process, with no demonstrated confidentiality or integrity impact. This issue is fixed in version 0.3.1.

CVE-2026-1187866.8 MÉD

—

———Improper input validation in non-secure-callable (NSC) veneer functions of the NXP MCUXpresso SDK rpmsg-lite multicore example (multicore_examples/rpmsg_lite_pingpong_tzm) up to releases 26.06.00-lts and 26.09.00 may allow a non-secure caller to supply unvalidated pointers and size values, potentially resulting in disclosure of secure-world memory to the non-secure domain, or denial of service. All software versions starting from 26.06.01-lts and 26.12.00-pvw1 have fixed this issue.5h CVE-2026-1187856.7 MÉD

———Improper handling of non-secure-world input in NSC veneer functions of NXP MCUXpresso SDK TrustZone-M examples (trustzone_examples), affecting versions through 26.06.00-lts and 26.09.00-pvw2, may allow a non-secure caller to supply unvalidated pointers or untrusted data, causing a timing side-channel, TOCTOU condition, or format-string misuse, potentially resulting in secure-world memory disclosure or denial of service. All software versions starting from 26.06.01-lts and 26.09.00 have fixed this issue.5h CVE-2026-1237917.3 ALT

———A vulnerability was detected in OpenBMB Internet of Agents up to 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. This affects the function _primary_field_query of the file common/utils/milvus_utils.py of the component Agent Registry. The manipulation of the argument key results in improper neutralization of special elements in data query logic. The attack may be launched remotely. The exploit is now public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The project was informed of the problem early through an issue report but has not responded yet.6h CVE-2026-978486.5 MÉD

——5A flaw was found in the token sanitization logic of Keycloak, an open source identity and access management solution. The issue occurs when a protocol mapper is configured to emit structured claims using the JSON type. The security check designed to remove unauthorized role mappings only looks for standard Java maps and fails to recognize Jackson based JSON objects. This allows an attacker to inject forged client roles into security tokens, which could lead to unauthorized access to protected resources.10h CVE-2026-487059.3 CRÍ

——13MONAI (Medical Open Network for AI) is an AI toolkit for health care imaging. Prior to 1.6.1, PydicomReader._get_affine() trusts non-finite values in the DICOM PixelSpacing, ImagePositionPatient, and ImageOrientationPatient fields and composes them into an affine matrix without validation. An unauthenticated attacker who can upload a crafted DICOM to a default MONAILabel deployment can propagate NaN or infinity values through LoadImaged, Spacingd, model inference, and output writing, causing inference failures, persistent datastore poisoning, or geometrically corrupted results. This issue is fixed in version 1.6.1.1d CVE-2026-463509.1 CRÍ

——15dcmjs is a JavaScript implementation of DICOM manipulation. Prior to 0.52.0, the DecimalString and IntegerString implementations in src/ValueRepresentation.js sanitize text with a permissive regular expression and pass the result to JavaScript's Number constructor without validating finiteness or the DICOM value-representation rules. Scientific notation overflow in a DS or IS field can produce positive or negative Infinity, while stripping alphabetic characters from signed infinity text can leave a sign-only string that converts to NaN. IntegerString also accepts exponent notation and values outside the DICOM signed 32-bit IS range. Applications that trust these parsed values can propagate invalid numbers into spatial geometry, display windowing, dose scaling, frame counts, rescaling, or volume reconstruction, causing incorrect calculations or disrupted processing. This issue is fixed in version 0.52.0.1d
