Debian DLA-1079-1 : libdbd-mysql-perl security update

critical Nessus Plugin ID 102887

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The 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.

CVE-2017-10788

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.

CVE-2017-10789

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libdbd-mysql-perl package.
