Release 3.10.2 of wolfSSL has bug fixes and new features including:

  • Poly1305 Windows macros fix. Thanks to GitHub user Jay Satiro
  • Compatibility layer expanded with multiple functions added
  • Improve fp_copy performance with ALT_ECC_SIZE
  • OCSP updates and improvements
  • Fixes for IAR EWARM 8 compiler warnings
  • Reduce stack usage with ECC_CACHE_CURVE disabled
  • Added ECC export raw for public and private key
  • Fix for NO_ASN_TIME build
  • Supported curves extensions now populated by default
  • Add DTLS build without big integer math
  • Fix for static memory feature with wc_ecc_verify_hash_ex and not SHAMIR
  • Added PSK interoperability testing to script bundled with wolfSSL
  • Fix for Python wrapper random number generation. Compiler optimizations with Python could place the random number in same buffer location each time. Thanks to GitHub user Erik Bray (embray)
  • Fix for tests on unaligned memory with static memory feature
  • Add macro WOLFSSL_NO_OCSP_OPTIONAL_CERTS to skip optional OCSP certificates
  • Sanity checks on NULL arguments added to wolfSSL_set_fd and wolfSSL_DTLS_SetCookieSecret

This release of wolfSSL fixes 2 low and 1 medium level security vulnerability.

Low level fix of buffer overflow for when loading in a malformed temporary DH file. Thanks to Yueh-Hsun Lin and Peng Li from KNOX Security, Samsung Research America for the report.

Medium level fix for processing of OCSP response. If using OCSP without hard faults enforced and no alternate revocation checks like OCSP stapling then it is recommended to update.

Low level fix for potential cache attack on RSA operations. If using wolfSSL RSA on a server that other users can have access to monitor the cache, then it is recommended to update wolfSSL. Thanks to Andreas Zankl, Johann Heyszl and Georg Sigl at Fraunhofer AISEC for the initial report.
