New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security update.
DescriptionThe Perl library for communicating with MySQL database, used in the 'mysql' commandline client is vulnerable to a man in the middle attack in SSL configurations and remote crash when connecting to hostile servers.
The DBD::mysql module through 4.042 for Perl allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact by triggering (1) certain error responses from a MySQL server or (2) a loss of a network connection to a MySQL server. The use-after-free defect was introduced by relying on incorrect Oracle mysql_stmt_close documentation and code examples.
The DBD::mysql module through 4.042 for Perl uses the mysql_ssl=1 setting to mean that SSL is optional (even though this setting's documentation has a 'your communication with the server will be encrypted' statement), which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, a related issue to CVE-2015-3152.
For Debian 7 'Wheezy', these problems have been fixed in version 4.021-1+deb7u3.
We recommend that you upgrade your libdbd-mysql-perl packages.
