Vulnerability Assessment Details

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

Vulnerability Assessment Summary
MySQL: Insecure temporary file creation in mysqlhotcopy

Detailed Explanation for this Vulnerability Assessment
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.
