| EnGarde Secure Linux Security Advisory October 19, 2001 |
| http://www.engardelinux.org/ ESA-20011019-01 |
| |
| Package: apache |
| Summary: Two apache 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, complete e-commerce using AllCommerce,
and integrated open source security tools.
OVERVIEW
- --------
There are two vulnerabilities in apache which can allow an
attacker to write to arbitrary files or view directory indexes when
they are not supposed to, in some configurations.
DETAIL
- ------
The following items are from the "Announcement" file included in the
Apache 1.3.22 tarball:
* A vulnerability was found in the split-logfile support program. A
request with a specially crafted Host: header could allow any file
with a .log extension on the system to be written to. PR#7848
CAN-2001-0730
* A vulnerability was found when Multiviews are used to negotiate
the directory index. In some configurations, requesting a URI with
a QUERY_STRING of M=D could return a directory listing rather than
the expected index page. CAN-2001-0731
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2001-0730 and CAN-2001-0731 to these issues.
SOLUTION
- --------
All users should upgrade to the most recent version, as outlined in
this advisory.
Guardian Digital recently made available the Guardian Digital Secure
Update, a means to proactively keep systems secure and manage
system software. EnGarde users can automatically update their system
using the Guardian Digital WebTool secure interface.
If choosing to manually upgrade this package, updates can 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 <filename>
To re-enable LIDS (if it was disabled), execute the command:
# /sbin/lidsadm -S -- +LIDS_GLOBAL
To verify the signature of the updated packages, execute the command:
# rpm -Kv <filename>
