[slackware-security]  mysql (SSA:2006-129-02)

New mysql packages are available for Slackware 10.2 and -current to
fix security issues.  The MySQL package shipped with Slackware 10.2
may possibly leak sensitive information found in uninitialized
memory to authenticated users.  The MySQL package previously in
Slackware -current also suffered from these flaws, but an additional
overflow could allow arbitrary code execution.

Since the vulnerabilities require a valid login and/or access to the
database server, the risk is moderate.  Slackware does not provide
network access to a MySQL database by default.


More details about the issues may be found in the Common
Vulnerabilities and Exposures (CVE) database.
Issues that affect both Slackware 10.2 and -current:
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1516
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1517

An issue affecting only Slackware -current:
  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1518


Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/mysql-4.1.19-i486-1.tgz:
  Upgraded to mysql-4.1.19.
  This fixes some minor security issues with possible information leakage.
  Note that the information leakage bugs require that the attacker have
  access to an account on the database.  Also note that by default,
  Slackware's rc.mysqld script does *not* allow access to the database
  through the outside network (it uses the --skip-networking option).
  If you've enabled network access to MySQL, it is a good idea to filter
  the port (3306) to prevent access from unauthorized machines.

    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1517
  (* Security fix *)
+--------------------------+

Here are the details from the Slackware -current ChangeLog:
+--------------------------+
ap/mysql-5.0.21-i486-1.tgz:  Upgraded to mysql-5.0.21.
  This fixes some security issues, including possible information leakage, and
  execution of arbitrary code.  Note that the information leakage bugs require
  that the attacker have access to an account on the database.  Also note that
  by default, Slackware's rc.mysqld script does *not* allow access to the
  database through the outside network (it uses the --skip-networking option).
