Ubuntu 6.06 LTS / 6.10 / 7.04 : mysql-dfsg-5.0 vulnerabilities (USN-528-1)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Neil Kettle discovered that MySQL could be made to dereference a NULL
pointer and divide by zero. An authenticated user could exploit this
with a crafted IF clause, leading to a denial of service.
(CVE-2007-2583)

Victoria Reznichenko discovered that MySQL did not always require the
DROP privilege. An authenticated user could exploit this via RENAME
TABLE statements to rename arbitrary tables, possibly gaining
additional database access. (CVE-2007-2691)

It was discovered that MySQL could be made to overflow a signed char
during authentication. Remote attackers could use crafted
authentication requests to cause a denial of service. (CVE-2007-3780)

Phil Anderton discovered that MySQL did not properly verify access
privileges when accessing external tables. As a result, authenticated
users could exploit this to obtain UPDATE privileges to external
tables. (CVE-2007-3782)

In certain situations, when installing or upgrading mysql, there was
no notification that the mysql root user password needed to be set. If
the password was left unset, attackers would be able to obtain
unrestricted access to mysql. This is now checked during mysql
start-up.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
