Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2008-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
USN-588-1 fixed vulnerabilities in MySQL. In fixing CVE-2007-2692 for
Ubuntu 6.06, additional improvements were made to make privilege
checks more restictive. As a result, an upstream bug was exposed which
could cause operations on tables or views in a different database to
fail. This update fixes the problem.
We apologize for the inconvenience.
Masaaki Hirose discovered that MySQL could be made to dereference a
NULL pointer. An authenticated user could cause a denial of service
(application crash) via an EXPLAIN SELECT FROM on the
INFORMATION_SCHEMA table. This issue only affects Ubuntu 6.06 and
Alexander Nozdrin discovered that MySQL did not restore
database access privileges when returning from SQL SECURITY
INVOKER stored routines. An authenticated user could exploit
this to gain privileges. This issue does not affect Ubuntu
Martin Friebe discovered that MySQL did not properly update
the DEFINER value of an altered view. An authenticated user
could use CREATE SQL SECURITY DEFINER VIEW and ALTER VIEW
statements to gain privileges. (CVE-2007-6303)
Luigi Auriemma discovered that yaSSL as included in MySQL
did not properly validate its input. A remote attacker could
send crafted requests and cause a denial of service or
possibly execute arbitrary code. This issue did not affect
Ubuntu 6.06 in the default installation. (CVE-2008-0226,
