| EnGarde Secure Linux Security Advisory October 03, 2002 |
| http://www.engardelinux.org/ ESA-20021003-022 |
| |
| Package: tar |
| Summary: directory traversal 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, complete e-commerce
using AllCommerce, and integrated open source security tools.
OVERVIEW
- --------
There is a directory traversal vulnerability in tar which may allow an
attacker to overwrite arbitrary files by tricking the administrator
into extracting a malicious archive.
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
