GLSA-200409-02 : MySQL: Insecure temporary file creation in mysqlhotcopy

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


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-200409-02
(MySQL: Insecure temporary file creation in mysqlhotcopy)

Jeroen van Wolffelaar discovered that the MySQL database hot copy utility
(mysqlhotcopy.sh), when using the scp method, uses temporary files with
predictable names. A malicious local user with write access to the /tmp
directory could create a symbolic link pointing to a file, which may then
be overwritten. In cases where mysqlhotcopy is run as root, a malicious
user could create a symlink to a critical file such as /etc/passwd and
cause it to be overwritten.

Impact :

A local attacker could use this vulnerability to destroy other users' data
or corrupt and destroy system files, possibly leading to a denial of
service condition.

Workaround :

There is no known workaround at this time.
