Gentoo Linux Security Advisory

Title: MySQL: Insecure temporary file creation in mysqlhotcopy (GLSA 200409-02)
Severity: normal
Exploitable: local
Date: September 01, 2004
Bug(s): #60744
ID: 200409-02

Synopsis

The mysqlhotcopy utility can create temporary files with predictable paths, allowing an attacker to use a symlink to trick MySQL into overwriting important data.

Background

MySQL is a popular open-source multi-threaded, multi-user SQL database server.

Affected Packages

Package: dev-db/mysql
Vulnerable: <= 4.0.20
Unaffected: >= 4.0.20-r1
Architectures: All supported architectures


Description

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.

Resolution

All MySQL users should upgrade to the latest version:
Code:
# emerge sync
# emerge -pv ">=dev-db/mysql-4.0.20-r1"
# emerge ">=dev-db/mysql-4.0.20-r1"
