{"id":"USN-2830-1","summary":"openssl vulnerabilities","details":"Guy Leaver discovered that OpenSSL incorrectly handled a ServerKeyExchange\nfor an anonymous DH ciphersuite with the value of p set to 0. A remote\nattacker could possibly use this issue to cause OpenSSL to crash, resulting\nin a denial of service. This issue only applied to Ubuntu 15.10.\n(CVE-2015-1794)\n\nHanno Böck discovered that the OpenSSL Montgomery squaring procedure\nalgorithm may produce incorrect results when being used on x86_64. A remote\nattacker could possibly use this issue to break encryption. This issue only\napplied to Ubuntu 15.10.
