OpenSSL CHANGES
_______________
+ Changes between 1.0.2f and 1.0.2g [1 Mar 2016]
+
+ * Disable weak ciphers in SSLv3 and up in default builds of OpenSSL.
+ Builds that are not configured with "enable-weak-ssl-ciphers" will not
+ provide any "EXPORT" or "LOW" strength ciphers.
+ [Viktor Dukhovni]
+
+ * Disable SSLv2 default build, default negotiation and weak ciphers. SSLv2
+ is by default disabled at build-time. Builds that are not configured with
+ "enable-ssl2" will not support SSLv2. Even if "enable-ssl2" is used,
+ users who want to negotiate SSLv2 via the version-flexible SSLv23_method()
+ will need to explicitly call either of:
+
+ SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2);
+ or
+ SSL_clear_options(ssl, SSL_OP_NO_SSLv2);
+
+ as appropriate. Even if either of those is used, or the application
+ explicitly uses the version-specific SSLv2_method() or its client and
+ server variants, SSLv2 ciphers vulnerable to exhaustive search key
+ recovery have been removed. Specifically, the SSLv2 40-bit EXPORT
+ ciphers, and SSLv2 56-bit DES are no longer available.
+ (CVE-2016-0800)
+ [Viktor Dukhovni]
+
+ *) Fix a double-free in DSA code
+
+ A double free bug was discovered when OpenSSL parses malformed DSA private
+ keys and could lead to a DoS attack or memory corruption for applications
+ that receive DSA private keys from untrusted sources. This scenario is
+ considered rare.
+
+ This issue was reported to OpenSSL by Adam Langley(Google/BoringSSL) using
+ libFuzzer.
+ (CVE-2016-0705)
+ [Stephen Henson]
+
+ *) Disable SRP fake user seed to address a server memory leak.
+
+ Add a new method SRP_VBASE_get1_by_user that handles the seed properly.
+
+ SRP_VBASE_get_by_user had inconsistent memory management behaviour.
+ In order to fix an unavoidable memory leak, SRP_VBASE_get_by_user
+ was changed to ignore the "fake user" SRP seed, even if the seed
+ is configured.
+
+ Users should use SRP_VBASE_get1_by_user instead. Note that in
+ SRP_VBASE_get1_by_user, caller must free the returned value. Note
+ also that even though configuring the SRP seed attempts to hide
+ invalid usernames by continuing the handshake with fake
+ credentials, this behaviour is not constant time and no strong
+ guarantees are made that the handshake is indistinguishable from
+ that of a valid user.
+ (CVE-2016-0798)
+ [Emilia Käsper]
+
+ *) Fix BN_hex2bn/BN_dec2bn NULL pointer deref/heap corruption
+
+ In the BN_hex2bn function the number of hex digits is calculated using an
+ int value |i|. Later |bn_expand| is called with a value of |i * 4|. For
+ large values of |i| this can result in |bn_expand| not allocating any
+ memory because |i * 4| is negative. This can leave the internal BIGNUM data
+ field as NULL leading to a subsequent NULL ptr deref. For very large values
+ of |i|, the calculation |i * 4| could be a positive value smaller than |i|.
+ In this case memory is allocated to the internal BIGNUM data field, but it
+ is insufficiently sized leading to heap corruption. A similar issue exists
+ in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn
+ is ever called by user applications with very large untrusted hex/dec data.
+ This is anticipated to be a rare occurrence.
+
+ All OpenSSL internal usage of these functions use data that is not expected
+ to be untrusted, e.g. config file data or application command line
+ arguments. If user developed applications generate config file data based
+ on untrusted data then it is possible that this could also lead to security
+ consequences. This is also anticipated to be rare.
+
+ This issue was reported to OpenSSL by Guido Vranken.
+ (CVE-2016-0797)
+ [Matt Caswell]
+
+ *) Fix memory issues in BIO_*printf functions
+
+ The internal |fmtstr| function used in processing a "%s" format string in
+ the BIO_*printf functions could overflow while calculating the length of a
+ string and cause an OOB read when printing very long strings.
+
+ Additionally the internal |doapr_outch| function can attempt to write to an
+ OOB memory location (at an offset from the NULL pointer) in the event of a
+ memory allocation failure. In 1.0.2 and below this could be caused where
+ the size of a buffer to be allocated is greater than INT_MAX. E.g. this
+ could be in processing a very long "%s" format string. Memory leaks can
+ also occur.
+
+ The first issue may mask the second issue dependent on compiler behaviour.
+ These problems could enable attacks where large amounts of untrusted data
+ is passed to the BIO_*printf functions. If applications use these functions
+ in this way then they could be vulnerable. OpenSSL itself uses these
+ functions when printing out human-readable dumps of ASN.1 data. Therefore
+ applications that print this data could be vulnerable if the data is from
+ untrusted sources. OpenSSL command line applications could also be
+ vulnerable where they print out ASN.1 data, or if untrusted data is passed
+ as command line arguments.
+
+ Libssl is not considered directly vulnerable. Additionally certificates etc
+ received via remote connections via libssl are also unlikely to be able to
+ trigger these issues because of message size limits enforced within libssl.
+
+ This issue was reported to OpenSSL Guido Vranken.
+ (CVE-2016-0799)
+ [Matt Caswell]
+
+ *) Side channel attack on modular exponentiation
+
+ A side-channel attack was found which makes use of cache-bank conflicts on
+ the Intel Sandy-Bridge microarchitecture which could lead to the recovery
+ of RSA keys. The ability to exploit this issue is limited as it relies on
+ an attacker who has control of code in a thread running on the same
+ hyper-threaded core as the victim thread which is performing decryptions.
+
+ This issue was reported to OpenSSL by Yuval Yarom, The University of
+ Adelaide and NICTA, Daniel Genkin, Technion and Tel Aviv University, and
+ Nadia Heninger, University of Pennsylvania with more information at
+ http://cachebleed.info.
+ (CVE-2016-0702)
+ [Andy Polyakov]
+
+ *) Change the req app to generate a 2048-bit RSA/DSA key by default,
+ if no keysize is specified with default_bits. This fixes an
+ omission in an earlier change that changed all RSA/DSA key generation
+ apps to use 2048 bits by default.
+ [Emilia Käsper]
+
Changes between 1.0.2e and 1.0.2f [28 Jan 2016]
*) DH small subgroups
[Emilia Käsper]
*) In DSA_generate_parameters_ex, if the provided seed is too short,
- return an error
+ use a random seed, as already documented.
[Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
