Details

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 6.10. (CVE-2006-7232)

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 7.10. (CVE-2007-2692)

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, CVE-2008-0227)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10

In general, a standard system upgrade is sufficient to effect the
necessary changes.
