Package        : libdbd-mysql-perl
Version        : 4.021-1+deb7u3
CVE ID         : CVE-2017-10788 CVE-2017-10789
Debian Bug     : 866818 866821

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.
