[Steve Henson] Changes between 1.0.2d and 1.0.2e [3 Dec 2015] *) BN_mod_exp may produce incorrect results on x86_64 There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. This issue was reported to OpenSSL by Hanno Böck. (CVE-2015-3193) [Andy Polyakov] *) Certificate verify crash with missing PSS parameter The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and absent mask generation function parameter. Since these routines are used to verify certificate signature algorithms this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. This issue was reported to OpenSSL by Loïc Jonas Etienne (Qnective AG). (CVE-2015-3194) [Stephen Henson] *) X509_ATTRIBUTE memory leak When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak memory. This structure is used by the PKCS#7 and CMS routines so any application which reads PKCS#7 or CMS data from untrusted sources is affected. SSL/TLS is not affected. This issue was reported to OpenSSL by Adam Langley (Google/BoringSSL) using libFuzzer. (CVE-2015-3195) [Stephen Henson] *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs. This changes the decoding behaviour for some invalid messages, though the change is mostly in the more lenient direction, and legacy behaviour is preserved as much as possible.
