Affected: MariaDB server, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support, Red Hat Hardened Images, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9

MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to the database using text protocol and big5 character set was vulnerable to SQL injections, even though mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19 and 3.4.9.

Affected: Ubuntu:26.04:LTS: mariadb

It was discovered that MariaDB did not properly validate parameters supplied by a joiner node during a State Snapshot Transfer using the mariabackup method. An attacker could possibly use this issue to execute arbitrary shell commands on the donor node. (CVE-2026-44168)

It was discovered that MariaDB did not properly enforce the SHOW CREATE ROUTINE privilege when a user obtained access to a stored routine via a role. An authenticated user could possibly use this issue to obtain sensitive information. (CVE-2026-44169)

It was discovered that MariaDB's mbstream utility did not properly validate paths when unpacking archives. An attacker could possibly use this issue to write files outside of the intended target directory. (CVE-2026-44171)

It was discovered that MariaDB's mysql_real_escape_string() function incorrectly handled the big5 character set. An attacker could possibly use this issue to perform SQL injection attacks. (CVE-2026-44172)

It was discovered that MariaDB did not properly check the FILE privilege when the FROM clause of a SELECT ... INTO OUTFILE or SELECT ... INTO DUMPFILE statement contained only subqueries. An authenticated user could possibly use this issue to write files to unintended locations. (CVE-2026-44173)

It was discovered that MariaDB did not properly validate parameters supplied by a joiner node during a State Snapshot Transfer using the rsync method. An attacker could possibly use this issue to execute arbitrary shell commands on the donor nod…
