Vulnerabilities

  • [Medium] CVE-2024-1544
    Potential ECDSA nonce side channel attack in versions of wolfSSL before 5.6.6 with wc_ecc_sign_hash calls. Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Analyzing the division through a control-flow revealing side-channel reveals a bias in the most significant bits of k. Depending on the curve this is either a negligible bias or a significant bias large enough to reconstruct k with lattice reduction methods. Thanks to Luca Wilke, Florian Sieck and Thomas Eisenbarth (University of Lübeck) for reporting the vulnerability. Details will appear in the proceedings of CCS 24.
    Fixed #7020

  • [Medium] CVE-2024-5288
    A private key blinding operation, enabled by defining the macro WOLFSSL_BLIND_PRIVATE_KEY, was added to mitigate a potential row hammer attack on ECC operations. If performing ECC private key operations in an environment where a malicious user could gain fine control over the device and perform row hammer style attacks it is recommended to update the version of wolfSSL used and to build with WOLFSSL_BLIND_PRIVATE_KEY defined. Thanks to Kemal Derya, M. Caner Tol, Berk Sunar for the report (Vernam Applied Cryptography and Cybersecurity Lab at Worcester Polytechnic Institute)
    Fixed in github pull request #7416

  • [Low] When parsing a provided maliciously crafted certificate directly using wolfSSL API, outside of a TLS connection, a certificate with an excessively large number of extensions could lead to a potential DoS. There are existing sanity checks during a TLS handshake with wolfSSL which mitigate this issue. Thanks to Bing Shi for the report.
    Fixed in github pull request #7597

  • [Low] CVE-2024-5991
    In the function MatchDomainName(), input param str is treated as a NULL terminated string despite being user provided and unchecked. Specifically, the Openssl compatibility function X509_check_host() takes in a pointer and length to check against, with no requirements that it be NULL terminated. While calling without a NULL terminated string is very uncommon, it is still technically allowed. If a caller was attempting to do a name check on a non*NULL terminated buffer, the code would read beyond the bounds of the input array until it found a NULL terminator.
    Fixed in github pull request #7604

  • [Medium] CVE-2024-5814
    A malicious TLS1.2 server can force a TLS1.3 client with downgrade capability to use a ciphersuite that it did not agree to and achieve a successful connection. This is because, aside from the extensions, the client was skipping fully parsing the server hello when downgrading from TLS 1.3.
    Fixed in github pull request #7619

  • [Medium] OCSP stapling version 2 response verification bypass issue when a crafted response of length 0 is received. Found with internal testing.
    Fixed in github pull request #7702

  • [Medium] OCSP stapling version 2 revocation bypass with a retry of a TLS connection attempt. A revoked CA certificate could incorrectly be loaded into the trusted signers list and used in a repeat connection attempt. Found with internal testing.
    Fixed in github pull request #7702
