| EnGarde Secure Linux Security Advisory February 20, 2003 |
| http://www.engardelinux.org/ ESA-20030220-004 |
| |
| Packages: MySQL, MySQL-client, MySQL-shared |
| Summary: MySQL double free vulnerability. |
+------------------------------------------------------------------------+
EnGarde Secure Linux is a secure distribution of Linux that features
improved access control, host and network intrusion detection, Web
based secure remote management, e-commerce, and integrated open source
security tools.
OVERVIEW
- --------
This update fixes a double free() bug in the MySQL daemon that could
allow an attacker, with a specially crafted MySQL client, to crash the
server. The attacker also requires a valid user account.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0073 to this issue.
All users are recommended to upgrade as soon as soon as possible.
SOLUTION
- --------
Users of the EnGarde Professional edition can use the Guardian Digital
Secure Network to update their systems automatically.
EnGarde Community users should upgrade to the most recent version
as outlined in this advisory. Updates may be obtained from:
ftp://ftp.engardelinux.org/pub/engarde/stable/updates/http://ftp.engardelinux.org/pub/engarde/stable/updates/
Before upgrading the package, the machine must either:
a) be booted into a "standard" kernel; or
b) have LIDS disabled.
To disable LIDS, execute the command:
# /sbin/lidsadm -S -- -LIDS_GLOBAL
To install the updated package, execute the command:
# rpm -Uvh files
You must now update the LIDS configuration by executing the command:
# /usr/sbin/config_lids.pl
To re-enable LIDS (if it was disabled), execute the command:
# /sbin/lidsadm -S -- +LIDS_GLOBAL
To verify the signatures of the updated packages, execute the command:
# rpm -Kv files
