Description

openssl vulnerabilities Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. 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 and Ubuntu 14.04 LTS as other releases were fixed in a previous security update. (CVE-2016-2177) It was discovered that OpenSSL did not properly handle Montgomery multiplication, resulting in incorrect results leading to transient failures. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7055) It was discovered that OpenSSL did not properly use constant-time operations when performing ECDSA P-256 signing. A remote attacker could possibly use this issue to perform a timing attack and recover private ECDSA keys. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-7056) Shi Lei discovered that OpenSSL incorrectly handled certain warning alerts. A remote attacker could possibly use this issue to cause OpenSSL to stop responding, resulting in a denial of service. (CVE-2016-8610) Robert Święcki discovered that OpenSSL incorrectly handled certain truncated packets. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2017-3731) It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2017-3732)
