MySQL 5.6.x < 5.6.36 Multiple Vulnerabilities (April 2017 CPU) (July 2017 CPU) (Riddle)
High Nessus Plugin ID 99512
Synopsis
The remote database server is affected by multiple vulnerabilities.
Description
The version of MySQL running on the remote host is 5.6.x prior to 5.6.36. It is, therefore, affected by multiple vulnerabilities :
- A carry propagation error exists in the OpenSSL component in the Broadwell-specific Montgomery multiplication procedure when handling input lengths divisible by but longer than 256 bits. This can result in transient authentication and key negotiation failures or reproducible erroneous outcomes of public-key operations with specially crafted input. A man-in-the-middle attacker can possibly exploit this issue to compromise ECDH key negotiations that utilize Brainpool P-512 curves. (CVE-2016-7055)
- An authentication information disclosure vulnerability, known as Riddle, exists due to authentication being performed prior to security parameter verification. A man-in-the-middle (MitM) attacker can exploit this vulnerability to disclose sensitive authentication information, which the attacker can later use for authenticating to the server. (CVE-2017-3305)
- Multiple unspecified flaws exist in the DML subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3308, CVE-2017-3456)
- Multiple unspecified flaws exist in the Optimizer subcomponent that allow an authenticated, remote attacker to cause a denial of service condition.
(CVE-2017-3309, CVE-2017-3452, CVE-2017-3453)
- An unspecified flaw exists in the Thread Pooling subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition.
(CVE-2017-3329)
- An unspecified flaw exists in the Memcached subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition. (CVE-2017-3450)
- Multiple unspecified flaws exist in the 'Security: Privileges' subcomponent that allow an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3461, CVE-2017-3462, CVE-2017-3463)
- An unspecified flaw exists in the DDL subcomponent that allows an authenticated, remote attacker to update, insert, or delete data contained in the database.
(CVE-2017-3464)
- An unspecified flaw exists in the Pluggable Auth subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition.
(CVE-2017-3599)
- An unspecified flaw exists in the 'Client mysqldump' subcomponent that allows an authenticated, remote attacker to execute arbitrary code. (CVE-2017-3600)
- An out-of-bounds read error exists in the OpenSSL component when handling packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers. An unauthenticated, remote attacker can exploit this, via specially crafted truncated packets, to cause a denial of service condition. (CVE-2017-3731)
- A carry propagating error exists in the OpenSSL component in the x86_64 Montgomery squaring implementation that may cause the BN_mod_exp() function to produce incorrect results. An unauthenticated, remote attacker with sufficient resources can exploit this to obtain sensitive information regarding private keys.
(CVE-2017-3732)
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 5.6.36 or later.
