| EnGarde Secure Linux Security Advisory February 19, 2003 |
| http://www.engardelinux.org/ ESA-20030219-003 |
| |
| Packages: php, mod_php |
| Summary: Several PHP vulnerabilities. |
+------------------------------------------------------------------------+
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
- --------
A heap-based buffer overflow vulnerability has been found in the
wordwrap() function of PHP. This vulnerability may cause a denial
of service attack or arbitrary code execution if wordwrap() is used on
untrusted input.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-1396 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
