CVE-2015-3193

The Montgomery squaring implementation in crypto/bn/asm/x86_64-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x86_64 platform, as used by the BN_mod_exp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key information via an attack against use of a (1) Diffie-Hellman (DH) or (2) Diffie-Hellman Ephemeral (DHE) ciphersuite.

These are all security issues fixed in the libopenssl-devel-1.0.2j-2.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libopenssl1_0_0-steam-1.0.2h-4.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libopenssl-1_1-devel-1.1.1l-1.2 package on the GA media of openSUSE Tumbleweed.

Guy Leaver discovered that OpenSSL incorrectly handled a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 15.10. (CVE-2015-1794)

Hanno Böck discovered that the OpenSSL Montgomery squaring procedure algorithm may produce incorrect results when being used on x86_64. A remote attacker could possibly use this issue to break encryption. This issue only applied to Ubuntu 15.10. (CVE-2015-3193)

Loïc Jonas Etienne discovered that OpenSSL incorrectly handled ASN.1 signatures with a missing PSS parameter. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2015-3194)

Adam Langley discovered that OpenSSL incorrectly handled malformed X509_ATTRIBUTE structures. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, resulting in a denial of service. (CVE-2015-3195)

It was discovered that OpenSSL incorrectly handled PSK identity hints. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-3196)
