pyasn1, a generic ASN.1 library for Python, decodes binary REAL values with a mantissa-building routine whose run time grows quadratically with the mantissa length. An attacker who can supply ASN.1 data to an application using pyasn1 can send a comparatively small REAL value that keeps a decoding process busy on one CPU core for seconds or longer. The attack works with BER, CER and DER decoding, with or without a schema, and leads to loss of availability.

pyasn1, a generic ASN.1 library for Python, consumes CPU quadratically when decoding constructed BIT STRING values with many fragments. An attacker who can supply crafted BER, CER or definite-length DER input can stall the decoding process. The flaw causes denial of service only, with no confidentiality or integrity impact, and applies only where an application parses untrusted ASN.1 data with pyasn1.

pyasn1, a generic ASN.1 library for Python, has a quadratic-time flaw when decoding constructed string types and indefinite-length ANY values in BER and CER data. An attacker who can supply such data to an application that decodes it can send many fragments, which exhausts CPU on the decoding workers. The issue causes denial of service only, with no confidentiality or integrity impact. Exposure depends on whether an application decodes untrusted ASN.1 input, and pyasn1 is often used as a transitive dependency.
pyasn1 · pyasn1
pyasn1 is a generic ASN.1 Python library. Versions from 0.3.3 up to 0.6.5 store the TagSet of every decoded component in a growing set during schemaless container decoding, which causes quadratic CPU work when attacker-supplied BER, CER or DER input contains many long tag IDs with colliding hashes. An unauthenticated remote attacker can send repeated crafted inputs to exhaust decoder CPU and reduce service availability.

Forge (node-forge) is a JavaScript implementation of TLS and cryptographic functions. Crafted DER or PEM input with deeply nested BIT STRINGs makes asn1.fromDer() consume excessive CPU time and memory, because the maxDepth limit was not applied to BIT STRING contents. A remote, unauthenticated attacker can exhaust resources and crash a Node.js process, so the impact is limited to availability. This is an incomplete fix of CVE-2025-66031.
Digitalbazaar · Forge (node-forge)
node-forge (Forge) versions before 1.4.1 accept a certificate as a CA when it contains a forged extension under the deprecated OIDs 2.5.29.10 or 2.5.29.13, placed before the genuine basicConstraints extension. An attacker who holds a certificate from a CA trusted by the application, where that CA copies extensions from certificate signing requests, can issue certificates for arbitrary names and impersonate servers or clients. Exploitation is complex and depends on such a trusted CA, and a public proof of concept exists.

Forge (node-forge) is a JavaScript implementation of TLS. A remote, unauthenticated peer can send a TLS record of another content type in the middle of a fragmented handshake message, which causes an uncaught TypeError in process(). This terminates the affected connection or the Node.js process hosting it, so the impact is limited to availability (CVSS 7.5, A:H). Exposure is highest for Node.js services that use forge's TLS code and accept connections from untrusted peers.

Forge (node-forge) is a JavaScript implementation of TLS. Before version 1.4.1, the TLS record processing in forge.tls.createConnection() handled each received record recursively, so a single input chunk with thousands of small records (for example heartbeat records) exhausts the JavaScript call stack. The attack needs no authentication and can be started by any peer that connects to a forge TLS server or to a server a forge TLS client connects to. In Node.js applications that call process() from a socket data handler, the uncaught exception terminates the process and drops the connections it serves.

A heap-based buffer overflow in the vtkWindBladeReader component of VTK 9.6.1 can be triggered by a specially crafted WindBlade .wind data set. A signed byteCount value in the binary data file can produce a zero-sized buffer, and out-of-bounds reads then follow. An attacker who can supply such a file to a vulnerable application can cause a deterministic denial of service and may expose heap-resident data.

A out-of-bounds read vulnerability in the vtkChacoReader InputGraph2 function of VTK 9.6.1 allows an attacker to read memory outside the intended buffer. The flaw is caused by missing validation of neighbor vertex IDs in Chaco graph files, which are later used as point indices. An attacker can trigger it by supplying a specially crafted Chaco file to an application that parses such input, which may lead to a crash or limited information disclosure.

The vtkBMPReader component of the VTK (Visualization Toolkit) library, version 9.6.1 according to the CNA, contains a memory corruption flaw when parsing BMP files with an unsupported bit depth. A specially crafted BMP file can cause a heap-buffer-overflow write, which can crash the application that opens the file. The attack requires that an application using VTK opens a malicious file, which is why exposure mainly concerns upload features or image-processing pipelines.

A memory corruption flaw (out-of-bounds write) in the vtkDEMReader ReadProfiles function of VTK 9.6.1 causes a heap buffer overflow when a specially crafted USGS DEM file is parsed. An attacker who can supply such a file to an application that uses VTK can trigger the flaw, which the advisory describes as an availability impact (crash or denial of service). No authentication is required, but the malicious file must reach the parser. Code execution has not been confirmed.

The PNG reader (vtkPNGReader::vtkPNGReaderUpdate2) of the Visualization Toolkit (VTK) 9.6 contains an invalid pointer dereference. A specially crafted PNG file can crash the process, causing a denial of service. An attacker only needs to supply the malicious file to the application, without authentication or user interaction, if the application accepts untrusted PNG files.

VTK 9.6 contains an invalid pointer dereference in vtkPNGReader::ExecuteInformation. A specially crafted PNG file can crash the process, causing a denial of service. The flaw is in error handling after a libpng longjmp, which can leave a dangling file pointer that is later passed to fclose(). The CVSS score of 7.5 reflects availability impact only, as the CNA rates it, but the NVD entry was still awaiting analysis at the time of writing.

A local attacker with low privileges can exploit an External Control of File Name or Path vulnerability in WiFiman Desktop to run arbitrary commands with root privileges on the host. The attacker must already have an account on the device, and internet exposure is not a factor. According to the CNA record, the macOS build is affected; the NVD entry was still awaiting analysis at the time of research.
Ubiquiti · WiFiman Desktop
WiFiman Desktop, a Wi-Fi diagnostic utility from Ubiquiti, binds to an unrestricted IP address. An attacker on the same network can exploit this to obtain information about the host device. The attack requires no authentication and no user interaction, but the impact is limited to confidentiality; remote code execution is not described.

HashiCorp Nomad and Nomad Enterprise follow symbolic links during same-client allocation data migration. A workload that can submit or update jobs can plant a symlink in a task-local directory, which Nomad preserves and later follows when setting directory permissions and ownership. On clients running as root, this can change permissions and ownership of host directories outside the allocation, enabling unauthorized access to host data, modification of host files and possibly privilege escalation (CVSS 8.8).

Forge (node-forge) is a JavaScript library implementing TLS and cryptography. Versions before 1.4.1 accept a PKCS#12 MAC or password-based encryption iteration count of zero, which makes the derived key a constant independent of the password and salt. An attacker can modify PKCS#12/PFX files or encrypted private keys and forge a valid MAC without knowing the password, so an application may accept an attacker's certificate and key. The attack requires no authentication, but only applies if the application parses such files from untrusted sources; confidentiality is not affected.
