| EnGarde Secure Linux Security Advisory March 7, 2003 |
| http://www.engardelinux.org/ ESA-20030307-008 |
| |
| Package: file |
| Summary: ELF parsing routine buffer overflow 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
- --------
There is a buffer overflow vulnerability in the 'file' command's ELF
parsing routines which can allow an attacker to exploit a victim by
tricking them into running 'file' on a specially crafted binary.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0102 to this issue.
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
