CVE-2025-30216 Information

Description

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. In versions 1.3.3 and prior a Heap Overflow vulnerability occurs in the Crypto_TM_ProcessSecurity function (crypto_tm.c:1735:8). When processing the Secondary Header Length of a TM protocol packet if the Secondary Header Length exceeds the packet’s total length a heap overflow is triggered during the memcpy operation that copies packet data into the dynamically allocated buffer p_new_dec_frame. This allows an attacker to overwrite adjacent heap memory potentially leading to arbitrary code execution or system instability. A patch is available at commit 810fd66d592c883125272fef123c3240db2f170f.
