GLSA-200409-02 : MySQL: Insecure temporary file creation in mysqlhotcopy
Medium Nessus Plugin ID 14649
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll MySQL users should upgrade to the latest version:
# emerge sync # emerge -pv '>=dev-db/mysql-4.0.20-r1' # emerge '>=dev-db/mysql-4.0.20-r1'
