Trustix Secure Linux Security Advisory #2004-0055
Package name: libxml2, postgresql

Date: 2004-10-29
Affected versions: Trustix Secure Linux 2.0
Trustix Secure Linux 2.1
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
libxml2:
This library allows to manipulate XML files. It includes support
to read, modify and write XML and HTML files.
postgresql:
PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including
transactions, subselects and user-defined types and functions).
Problem description:
libxml2:
Sean reported the following issues to
Bugtraq:
1)There is a buffer overflow when parsing a URL with ftp information
in it. A loop incorrectly copies data from a user supplied buffer
into a finite stack buffer with no regard for the length being copied.
2)There is a buffer overflow when parsing a proxy URL with ftp
information in it. A loop incorrectly copies data from a user supplied
buffer into a finite stack buffer with no regard for the length being
copied.
3)There are multiple buffer overflows in the code that resolves names
via DNS. An attacker running a malicious DNS server, or an attacker
on a LAN spoofing DNS replies could leverage these to execute code on
the victim's computer.
postgresql:
According to the release notice, this update fixes the following possible
data loss bug:
Repair possible failure to update hint bits on disk.
Under rare circumstances this oversight could lead to "could not
access transaction status" failures, which qualifies it as a
potential-data-loss bug.
Action:
We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.
