Cryptolib

CryptoLib versions prior to 1.4.3 contain a heap buffer overflow in the KMC crypto service's Base64 decoder, where oversized input strings can write beyond allocated buffer boundaries when processing KMC JSON responses. An attacker with network access to the KMC service can trigger this vulnerability to crash the spacecraft-ground station communication process or potentially execute arbitrary code. Public exploit code exists for this vulnerability, and no patch is currently available.

Heap buffer overflow in CryptoLib versions prior to 1.4.3 allows a high-privileged local attacker to corrupt adjacent memory by supplying oversized hex strings in MariaDB SA fields without capacity validation. Public exploit code exists for this vulnerability affecting spacecraft communication security implementations. The flaw enables denial of service and potential code execution through heap memory manipulation.

CryptoLib versions prior to 1.4.3 are vulnerable to denial of service through unbounded memory allocation in the KMC crypto service client's HTTP response handling. A malicious or compromised KMC server can trigger excessive memory consumption by sending arbitrarily large responses, causing the client process to crash. Public exploit code exists for this vulnerability affecting spacecraft communications secured by SDLS-EP.

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. The issue is resolved in version 1.4.3 and later.

CryptoLib versions prior to 1.4.3 contain an out-of-bounds heap read in the cryptography_aead_encrypt() function, affecting spacecraft communications secured via the SDLS-EP protocol. Public exploit code exists for this vulnerability, allowing remote attackers to trigger a denial of service condition without authentication. The vulnerability impacts systems using CryptoLib for ground-to-spacecraft communications and has been patched in version 1.4.3.

CryptoLib versions prior to 1.4.3 suffer from an out-of-bounds heap read in the cryptography_encrypt() function when processing malformed JSON metadata from KMC servers, allowing remote attackers to trigger a denial of service condition. The vulnerability stems from improper buffer boundary checking during string parsing in spacecraft-ground station communications secured by the SDLS-EP protocol. Public exploit code exists for this medium-severity flaw, though a patch is available.

CryptoLib versions prior to 1.4.3 contain an out-of-bounds read vulnerability in the base64urlDecode function that dereferences memory before validating input parameters, potentially causing a denial of service in spacecraft communications secured by SDLS-EP. Affected systems running cFS with vulnerable CryptoLib versions could crash when processing malformed base64 input. Public exploit code exists for this vulnerability, though no patch is currently available.

CryptoLib versions prior to 1.4.3 contain an out-of-bounds read vulnerability in the Crypto_AOS_ProcessSecurity function that allows remote attackers to crash spacecraft communications systems when parsing malformed AOS frame hashes. Public exploit code exists for this vulnerability affecting cFS deployments that rely on SDLS-EP for spacecraft-to-ground station security. The vulnerability has high severity due to its denial of service impact on critical space communications infrastructure, and no patch is currently available.

Out-of-bounds write in CryptoLib's SDLS-EP implementation allows unauthenticated network attackers to corrupt the gvcid_counter variable by writing beyond array bounds during parameter registration, potentially disrupting spacecraft-to-ground station communications security. Affected systems running CryptoLib versions prior to 1.4.3 are vulnerable to manipulation of parameter lookup logic without authentication or user interaction. No patch is currently available for this vulnerability affecting NASA's core Flight System deployments.
