 mbed TLS ChangeLog (Sorted per branch, date)
 
+= mbed TLS 2.4.2 branch released 2017-03-08
+
+Security
+   * Add checks to prevent signature forgeries for very large messages while
+     using RSA through the PK module in 64-bit systems. The issue was caused by
+     some data loss when casting a size_t to an unsigned int value in the
+     functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
+     mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
+   * Fixed potential livelock during the parsing of a CRL in PEM format in
+     mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
+     characters after the footer could result in the execution of an infinite
+     loop. The issue can be triggered remotely. Found by Greg Zaverucha,
+     Microsoft.
+   * Removed MD5 from the allowed hash algorithms for CertificateRequest and
+     CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
+     Introduced by interoperability fix for #513.
+   * Fixed a bug that caused freeing a buffer that was allocated on the stack,
+     when verifying the validity of a key on secp224k1. This could be
+     triggered remotely for example with a maliciously constructed certificate
+     and potentially could lead to remote code execution on some platforms.
+     Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
+     team. #569 CVE-2017-2784
+
+Bugfix
+   * Fix output certificate verification flags set by x509_crt_verify_top() when
+     traversing a chain of trusted CA. The issue would cause both flags,
+     MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
+     set when the verification conditions are not met regardless of the cause.
+     Found by Harm Verhagen and inestlerode. #665 #561
+   * Fix the redefinition of macro ssl_set_bio to an undefined symbol
+     mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
+     Found by omlib-lin. #673
+   * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
+     x509_csr.c that are reported when building mbed TLS with a config.h that
+     does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
+   * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
+     would compare 64 bits of the record counter instead of 48 bits as indicated
+     in RFC 6347 Section 4.3.1. This could cause the execution of the
+     renegotiation routines at unexpected times when the protocol is DTLS. Found
+     by wariua. #687
+   * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
+     the input string in PEM format to extract the different components. Found
+     by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_ctr_drbg_reseed() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could
+     cause buffer bound checks to be bypassed. Found by Eyal Itkin.
+   * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
+     Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
+   * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
+     by missing calls to mbedtls_pem_free() in cases when a
+     MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
+     fix proposed by Guido Vranken. #722
+   * Fixed the templates used to generate project and solution files for Visual
+     Studio 2015 as well as the files themselves, to remove a build warning
+     generated in Visual Studio 2015. Reported by Steve Valliere. #742
+   * Fix a resource leak in ssl_cookie, when using MBEDTLS_THREADING_C.
+     Raised and fix suggested by Alan Gillingham in the mbed TLS forum. #771
+   * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
+     number to write in hexadecimal is negative and requires an odd number of
+     digits. Found and fixed by Guido Vranken.
+   * Fix unlisted DES configuration dependency in some pkparse test cases. Found
+     by inestlerode. #555
