GLSA-200405-20 : Insecure Temporary File Creation In MySQL

low Nessus Plugin ID 14506

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200405-20 (Insecure Temporary File Creation In MySQL)

 The MySQL bug reporting utility (mysqlbug) creates a temporary file to log bug reports to. A malicious local user with write access to the /tmp directory could create a symbolic link of the name mysqlbug-N pointing to a protected file, such as /etc/passwd, such that when mysqlbug creates the Nth log file, it would end up overwriting the target file. A similar vulnerability exists with the mysql_multi utility, which creates a temporary file called mysql_multi.log.
 Impact :

 Since mysql_multi runs as root, a local attacker could use this to destroy any other users' data or corrupt and destroy system files.
 Workaround :

 One could modify both scripts to log to a directory that users do not have write permission to, such as /var/log/mysql/.

Solution

All users should upgrade to the latest stable version of MySQL.
 # emerge sync # emerge -pv '>=dev-db/mysql-4.0.18-r2' # emerge '>=dev-db/mysql-4.0.18-r2'
