Description:
Several vulnerabilities including insecure handling of temporary files
and arbitrary code execution have been discovered in the MySQL RDBMS [0].
Javier Fernandez-Sanguino Pena found that users may overwrite
arbitrary files or read temporary files via a symlink attack on
insecurely created temporary files. The Common Vulnerabilities and
Exposures (CVE) project assigned the identifier CAN-2005-0004 [1] to
this problem.
Stefano Di Paola found that users may load forbidden dynamic library
symbols with dlsym(3) to exploit a problem with user definable
functions (UDFs) logic and thereby remotely execute arbitrary code.
The Common Vulnerabilities and Exposures (CVE) project assigned the
identifier CAN-2005-0709 [2] to this problem.
Stefano Di Paola also determined that incomplete testing of dynamic
library pathnames could lead to insecure loading of UDFs from dynamic
libraries in arbitrary locations, allowing users to remotely execute
arbitrary code. The Common Vulnerabilities and Exposures (CVE) project
assigned the identifier CAN-2005-0710 [3] to this problem.
Stefano Di Paola also discovered that creation of temporary tables
uses predictable file names, allowing users to overwrite arbitrary
files via a symlink attack. The Common Vulnerabilities and Exposures
(CVE) project assigned the identifier CAN-2005-0711 [4] to this
problem.
Please check whether you are affected by running "<prefix>/bin/openpkg
rpm -q mysql". If you have the "mysql" package installed and its
version is affected (see above), we recommend that you immediately
upgrade it (see Solution) and its dependent packages (see above). [5][6]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[7], fetch it from the OpenPKG FTP service [8] or a mirror location,
verify its integrity [9], build a corresponding binary RPM from it
[5] and update your OpenPKG installation by applying the binary RPM
[6]. For the most previous release OpenPKG 2.2, perform the following
operations to permanently fix the security problem.
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.2/UPD
ftp> get mysql-4.0.21-2.2.2.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig mysql-4.0.21-2.2.2.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild mysql-4.0.21-2.2.2.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/mysql-4.0.21-2.2.2.*.rpm
Additionally, we recommend rebuilding and reinstalling all dependent
packages (see above) as well [5][6].
