Synopsis
A vulnerability was discovered in MariaDB and MySQL which may allow local users to gain root privileges.Background
MySQL is a popular multi-threaded, multi-user SQL server. MariaDB is an enhanced, drop-in replacement for MySQL.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
dev-db/mariadb | < 10.0.30-r1 | >= 10.0.30-r1 | All supported architectures |
dev-db/mysql | < 5.6.36-r1 | >= 5.6.36-r1 | All supported architectures |
Description
The Gentoo installation scripts before 2017-09-29 have chown calls for user-writable directory trees, which allows local users to gain privileges by leveraging access to the mysql account for creation of a link.
Impact
A local attacker could escalate privileges to root.
Workaround
There is no known workaround at this time.
Resolution
All MariaDB users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.0.30-r1"
All MySQL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/mysql-5.6.36-r1"
