MariaDB Server 5.5.x < 5.5.54 Multiple Vulnerabilities

High

Synopsis

The remote database server is affected by multiple attack vectors.

Description

MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 5.5.x earlier than 5.5.54, and is therefore affected by multiple vulnerabilities :

- A flaw exists in 'scripts/mysqld_safe.sh' that is triggered when handling arguments to 'malloc-lib'. This may allow a local attacker to potentially gain elevated privileges. (OSVDB 146606) - A flaw exists in 'sql/item_subselect.cc' that is triggered during the handling of queries from the select/unit tree. This may allow an authenticated attacker to crash the database. (OSVDB 149068) - A flaw exists in the 'Item::check_well_formed_result()' function in 'sql/item.cc' that is triggered during the handling of row validation. This may allow an authenticated attacker to crash the database. (OSVDB 149069) - A flaw exists in the 'Rpl_filter::parse_filter_rule()' function in 'sql/rpl_filter.cc' that is triggered during the clearing of wildcards. This may allow an authenticated attacker to crash the database. (OSVDB 149071) - A flaw exists in the 'lex_one_token()' function in 'sql/sql_lex.cc' that is triggered during the handling of a specially crafted query. This may allow an authenticated attacker to crash the database. (OSVDB 149106) - A flaw exists in the 'merge_buffers()' function in 'sql/filesort.cc' that is triggered during the handling of 'sort_union' optimization. This may allow an authenticated attacker to crash the database. (OSVDB 149347) - A flaw exists in the 'Item_cache::safe_charset_converter()' function in 'sql/item.cc' that is triggered during the handling of a specially crafted subselect query item. This may allow an authenticated attacker to crash the database. (OSVDB 149351) - A flaw exists in the 'st_select_lex::is_merged_child_of()' function in 'sql/sql_lex.cc' that is triggered when handling merged views or derived tables. This may allow an authenticated attacker to crash the database. (OSVDB 149352) - A flaw exists in 'sql/item.cc' that is triggered during the handling of a specially crafted subquery. This may allow an authenticated attacker to crash the database. (OSVDB 149353) - A flaw exists in 'scripts/mysqld_safe.sh' related to insecure use of certain shell utilities e.g. chown and rm when handling error log files. This may allow a local attacker via a symlink attack to gain 'root' privileges. (OSVDB 150449) - An unspecified flaw exists related to the DDL subcomponent. This may allow an authenticated attacker to cause a denial of service. No further details have been provided by the vendor. (OSVDB 150450) - An unspecified flaw exists related to the DML subcomponent. This may allow an authenticated attacker to cause a denial of service. No further details have been provided by the vendor. (OSVDB 150452) - An unspecified flaw exists related to the 'Server:Optimizer' subcomponent. This may allow an authenticated attacker to cause a denial of service. No further details have been provided by the vendor. (OSVDB 150454) - A flaw exists in 'scripts/mysqld_safe.sh' related to handling of the '--ledir' command line option used to specify the directory where mysqld is stored, as this value may be read from the configuration file. This may allow a local attacker to gain elevated privileges. (OSVDB 150456) - A flaw exists in the 'packaging/rpm-oel/mysql.init' initialization script related to insecure use of the chown and chmod utilities. This may allow a local attacker to potentially gain 'root' privileges. (OSVDB 150457) - An unspecified flaw exists related to the Logging subcomponent. This may allow a local attacker to cause a denial of service. No further details have been provided by the vendor. (OSVDB 150463) - An unspecified flaw exists related to the Error Handling subcomponent. This may allow a local attacker to gain access to sensitive information. No further details have been provided by the vendor. (OSVDB 150464)

Solution

Upgrade to version 5.5.54 or later.
