CVE-2024-44911
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNASA CryptoLib v1.3.0 was discovered to contain an Out-of-Bounds read via the TC subsystem (crypto_tc.c).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNASA CryptoLib v1.3.0 contains an out-of-bounds read vulnerability in the TC subsystem (crypto_tc.c). This memory safety issue allows reading memory beyond allocated buffer boundaries, potentially exposing sensitive data or causing denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify NASA CryptoLib versionCheck the version header file, library metadata, or version definition in the codebase (e.g., look for VERSION, CRYPTOLIB_VERSION, or check CMakeLists.txt, setup.py, or a version.h file)Affected if Installed version is exactly 1.3.0
-
Verify crypto_tc.c is present in the buildSearch for the file crypto_tc.c in the source tree or compiled object files. Check if it is included in the build system (CMake, Makefile, or build configuration)Affected if The crypto_tc.c file exists and is compiled into the deployed library or binary
-
Confirm TC subsystem is enabledReview the application configuration, initialization code, or build flags to determine if the TC (Telecommand) processing subsystem is being used (look for TC_ENABLE, USE_TC, or similar configuration options)Affected if TC subsystem initialization or processing code is executed at runtime
-
Inspect the vulnerable code path in crypto_tc.cExamine the crypto_tc.c source file around the buffer handling routines where out-of-bounds read occurs. Look for functions handling TC frame parsing, PDU processing, or memory access operations without proper bounds validationAffected if The code contains the unchecked buffer access patterns described in the vulnerability (reading beyond allocated buffer boundaries)
-
Check for deployed binaries or librariesIf using a pre-built library, inspect the library binary or its associated version manifest to confirm it was built from NASA CryptoLib v1.3.0Affected if The deployed library binary matches version 1.3.0
A system is affected if it runs NASA CryptoLib version 1.3.0 with the TC subsystem (crypto_tc.c) compiled and enabled, where the vulnerable out-of-bounds read code path in the TC processing is executed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version of NASA CryptoLib if available, otherwise audit and add proper bounds checking in the crypto_tc.c TC subsystem code to prevent out-of-bounds memory reads.
