FreeBSD-SN-02:05 Security Notice
The FreeBSD Project
Topic: security issues in ports
Announced: 2002-08-28
I. Introduction
Several ports in the FreeBSD Ports Collection are affected by security
issues. These are listed below with references and affected versions.
All versions given refer to the FreeBSD port/package version numbers.
The listed vulnerabilities are not specific to FreeBSD unless
otherwise noted.
These ports are not installed by default, nor are they ``part of
FreeBSD'' as such. The FreeBSD Ports Collection contains thousands of
third-party applications in a ready-to-install format. FreeBSD makes
no claim about the security of these third-party applications. See
<URL:http://www.freebsd.org/ports/>; for more information about the
FreeBSD Ports Collection.
II. Ports
+------------------------------------------------------------------------+
Port name: acroread5
Affected: versions < acroread-5.06
Status: Fixed
Insecure temporary file handling. The acrobatviewer, acroread4,
ghostscript, gv, mgv and xpdf ports can also display PDF files.
<URL:http://online.securityfocus.com/archive/1/278984>;
<URL:http://online.securityfocus.com/archive/1/284263>;
+------------------------------------------------------------------------+
Port name: aide
Affected: versions < aide-0.7_1
Status: Fixed
The default aide.conf silently fails to check subdirectories, even
though it appears to be configured to do so.
+------------------------------------------------------------------------+
Port name: apache+mod_ssl
Affected: versions < 1.3.26+2.8.10
Status: Fixed
A child process of the Apache server can crash if it receives a
request for the contents of a directory in which a maliciously
constructed .htaccess file has been placed. In the default
configuration, another child will be spawned, and the crash will
be logged. Therefore the bug should be insignificant for most
users.

+------------------------------------------------------------------------+
Port name: bugzilla
Affected: versions < bugzilla-2.14.2

Port name: Canna
Affected: versions < ja-Canna-3.5b2_3
Status: Fixed

daemon. Although previously corrected, the patch containing the
correction was inadvertently removed from the port skeleton.

+------------------------------------------------------------------------+
Port name: linux-netscape6, netscape7, linux-mozilla, and mozilla
Affected: versions < mozilla-1.0_1,1 (mozilla)
versions < linux-mozilla-1.1 (linux-mozilla)
All versions (others)
Status: Fixed (linux-mozilla and mozilla)
Not fixed (others)
Malicious Web pages or files can cause loss of X session.
When the X server receives a request to display an enormously large
scalable font, the server exits abruptly, killing all its clients.
This has been confirmed only with XFree86 4.2.0, but there is
evidence that XFree86 3.3.6, the X font server, and Xvnc behave the
same way. Unpatched Netscape (major version 6 or 7) and Mozilla
browsers do not limit the size of fonts which Web pages or files
can specify, thus triggering the bug.
Scalable fonts may be disabled as a workaround.
<URL:http://bugzilla.mozilla.org/show_bug.cgi?id=150339>;
+------------------------------------------------------------------------+
Port name: mm
Affected: versions < mm-1.2.0

Affected: versions < mpack-1.5_2
Status: Fixed
Buffer overflow which might be triggered when mpack is used to process
data from a remote source (email, news, and so on).
<URL:http://www.linuxsecurity.com/advisories/debian_advisory-2241.html>;
+------------------------------------------------------------------------+
Port name: mozilla, linux-mozilla
Affected: versions < mozilla-1.0.rc1_2,1 (mozilla)
versions < linux-mozilla-1.0_1 (linux-mozilla)
Status: Not fixed
An overflow exists in the Chatzilla IRC client. It can cause Mozilla
to crash even if the demonstration page does not cause the crash.
According to Robert Ginda, the bug does not allow execution of
malicious code.

III. Upgrading Ports/Packages
To upgrade a fixed port/package, perform one of the following:
1) Upgrade your Ports Collection and rebuild and reinstall the port.
Several tools are available in the Ports Collection to make this
easier. See:
/usr/ports/devel/portcheckout
/usr/ports/misc/porteasy
/usr/ports/sysutils/portupgrade
2) Deinstall the old package and install a new package obtained from
[i386]
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/All/
Packages are not automatically generated for other architectures at
this time.

FreeBSD Security Notices are communications from the Security Officer
intended to inform the user community about potential security issues,
such as bugs in the third-party applications found in the Ports
Collection, which will not be addressed in a FreeBSD Security
Advisory.
Feedback on Security Notices is welcome at <security-officer@FreeBSD.org>.
