Oracle MySQL 5.7.x < 5.7.12 Multiple Vulnerabilities (RPM Check) (April 2016 CPU) (July 2016 CPU) (October 2017 CPU) (DROWN)

critical Nessus Plugin ID 90834

Synopsis

The remote host is missing one or more security updates.

Description

The version of Oracle MySQL installed on the remote host is 5.7.x prior to 5.7.12. It is, therefore, affected by the following vulnerabilities :

- A cipher algorithm downgrade vulnerability exists in the bundled version of OpenSSL due to a flaw that is triggered when handling cipher negotiation. A remote attacker can exploit this to negotiate SSLv2 ciphers and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled on the server. Note that this vulnerability only exists if the SSL_OP_NO_SSLv2 option has not been disabled. (CVE-2015-3197)

- An unspecified flaw exists in the Pluggable Authentication subcomponent that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2016-0639)

- An unspecified flaw exists in the Federated subcomponent that allows a local attacker to impact integrity and availability. (CVE-2016-0642)

- An unspecified flaw exists in the DML subcomponent that allows a local attacker to disclose potentially sensitive information. (CVE-2016-0643)

- An unspecified flaw exists in the FTS subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0647)

- An unspecified flaw exists in the PS subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0648)

- An unspecified flaw exists in the InnoDB subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0655)

- An unspecified flaw exists in the JSON subcomponent that allows a local attacker to disclose potentially sensitive information. (CVE-2016-0657)

- An unspecified flaw exists in the Optimizer subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0659)

- An unspecified flaw exists in the Partition subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0662)

- An unspecified flaw exists in the Security: Privileges subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0666)

- An unspecified flaw exists in the Locking subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2016-0667)

- A key disclosure vulnerability exists in the bundled version of OpenSSL due to improper handling of cache-bank conflicts on the Intel Sandy-bridge microarchitecture. An attacker can exploit this to gain access to RSA key information. (CVE-2016-0702)

- A double-free error exists in the bundled version of OpenSSL due to improper validation of user-supplied input when parsing malformed DSA private keys. A remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0705)

- A NULL pointer dereference flaw exists in the bundled version of OpenSSL in the BN_hex2bn() and BN_dec2bn() functions. A remote attacker can exploit this to trigger a heap corruption, resulting in the execution of arbitrary code. (CVE-2016-0797)

- A denial of service vulnerability exists in the bundled version of OpenSSL due to improper handling of invalid usernames. A remote attacker can exploit this, via a specially crafted username, to leak 300 bytes of memory per connection, exhausting available memory resources.
(CVE-2016-0798)

- Multiple memory corruption issues exist in the bundled version of OpenSSL that allow a remote attacker to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-0799)

- A flaw exists in the bundled version of OpenSSL that allows a cross-protocol Bleichenbacher padding oracle attack known as DROWN (Decrypting RSA with Obsolete and Weakened eNcryption). This vulnerability exists due to a flaw in the Secure Sockets Layer Version 2 (SSLv2) implementation, and it allows captured TLS traffic to be decrypted. A man-in-the-middle attacker can exploit this to decrypt the TLS connection by utilizing previously captured traffic and weak cryptography along with a series of specially crafted connections to an SSLv2 server that uses the same private key. (CVE-2016-0800)

- A man-in-the-middle spoofing vulnerability exists due to the server hostname not being verified to match a domain name in the Subject's Common Name (CN) or SubjectAltName field of the X.509 certificate. A man-in-the-middle attacker can exploit this, by spoofing the TLS/SSL server via a certificate that appears valid, to disclose sensitive information or manipulate transmitted data.
(CVE-2016-2047)

- An unspecified flaw exists in the Optimizer subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-3440, CVE-2017-10378)

- An unspecified flaw exists in the Connection subcomponent that allows an unauthenticated, remote attacker to disclose potentially sensitive information.
(CVE-2016-5444)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MySQL version 5.7.12 or later.
