Ubuntu Security Notice 588-2 - 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 restrictive. 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.
7b3e0c3b9aac237bc56c8aa95c0492465ee731361e13d7ca3e16a16caaa29be0Ubuntu Security Notice 588-1 - 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. 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. 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. 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.
5a8255800f0f13ab0170873f78aa7381ffe3fa764291a6fe05ed17d87fae4f3fMandriva Linux Security Advisory - The mysql_change_db() function in MySQL 5.0.x before 5.0.40 did not restore THD::db_access privileges when returning from SQL SECURITY INVOKER stored routines, which allowed remote authenticated users to gain privileges. The federated engine in MySQL 5.0.x, when performing a certain SHOW TABLE STATUS query, did not properly handle a response with a small number of columns, which could allow a remote MySQL server to cause a denial of service (federated handler crash and daemon crash) via a response that lacks the minimum required number of columns.
