<title>MySQL: Insecure temporary file creation in mysqlhotcopy</title>
|
|
<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.

|
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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

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"</code>
