CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Lifecycle Timeline
4Description
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, the cryptography_encrypt() function allocates multiple buffers for HTTP requests and JSON parsing that are never freed on any code path. Each call leaks approximately 400 bytes of memory. Sustained traffic can gradually exhaust available memory. This issue has been patched in version 1.4.3.
Analysis
CryptoLib versions prior to 1.4.3 leak approximately 400 bytes of memory with each call to the cryptography_encrypt() function due to unfreed buffers, allowing remote attackers to conduct denial-of-service attacks against spacecraft-to-ground communications by exhausting available memory through sustained traffic. Public exploit code exists for this vulnerability. …
