PARTIAL Summary
The mysql_change_db function in MySQL 5.0.x before 5.0.40 and 5.1.x before 5.1.18 does not restore THD::db_access privileges when returning from SQL SECURITY INVOKER stored routines, which allows remote authenticated users to gain privileges.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-588-1.NASL description 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). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 31638 published 2008-03-21 reporter Ubuntu Security Notice (C) 2008-2019 Canonical, Inc. / NASL script (C) 2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/31638 title Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : mysql-dfsg-5.0 vulnerabilities (USN-588-1) NASL family Databases NASL id MYSQL_5_1_18.NASL description The version of MySQL installed on the remote host reportedly is affected by several issues : - Evaluation of an last seen 2020-06-01 modified 2020-06-02 plugin id 25242 published 2007-05-17 reporter This script is Copyright (C) 2007-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/25242 title MySQL 5.1 < 5.1.18 Multiple Vulnerabilities NASL family Databases NASL id MYSQL_SELECT_IF_DOS.NASL description The version of MySQL installed on the remote host reportedly is affected by a denial of service vulnerability that may be triggered with a specially crafted IF query.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2007-2583 The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40 allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference. (Affects source version 5.0.32.) - CVE-2007-2691 MySQL does not require the DROP privilege for RENAME TABLE statements, which allows remote authenticated users to rename arbitrary tables. (All supported versions affected.) - CVE-2007-2692 The mysql_change_db function does not restore THD::db_access privileges when returning from SQL SECURITY INVOKER stored routines, which allows remote authenticated users to gain privileges. (Affects source version 5.0.32.) - CVE-2007-3780 MySQL could be made to overflow a signed char during authentication. Remote attackers could use specially crafted authentication requests to cause a denial of service. (Upstream source versions 4.1.11a and 5.0.32 affected.) - CVE-2007-3782 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. (Affects source version 5.0.32.) - CVE-2007-5925 The convert_search_mode_to_innobase function in ha_innodb.cc in the InnoDB engine in MySQL 5.1.23-BK and earlier allows remote authenticated users to cause a denial of service (database crash) via a certain CONTAINS operation on an indexed column, which triggers an assertion error.

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.

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 (CVE-2007-6304). The updated packages provide MySQL 5.0.45 for all Mandriva Linux platforms that shipped with MySQL 5.0.x which offers a number of feature enhancements and bug fixes.
