Turbolinux Security Announcement
Package: gnupg
Vulnerable Packages: All Turbolinux versions previous to 1.0.6-1
Date: 06/06/2001 5:00 PDT
Affected Turbolinux platforms: TL 6.5 Server,
TL 6.1 Workstation,
All Turbolinux versions
6.0.5 and earlier
Turbolinux Advisory ID#: TLSA2001028

_________________________________________________________________________
Security holes have been discovered in the package gnupg, the GPG encryp-
tion program. Please update this package in your installation as soon as
possible.
_________________________________________________________________________
1. Problem Summary
a. Format String Vulnerability
An indirect invocation of the function vfprintf() does not pass
the argument "%s" as the first argument. This allows for a filename
to use format strings and may allow a user with malicious intent to
invoke shell commands with the current user's privileges.
b. Private Key Retrieval Vulnerability
It has been determined that there are insufficient measures taken
in protecting a user's secret key. If an attacker has write access
to a user's private key file, and is able to capture a message that
is signed with that private key, he will be able to decipher the
user's private key. Note that this is done even without knowledge
of the user's secret passphrase.
2. Solution
Update the package from our ftp server by running the following command:
rpm -Uvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gnupg-1.0.6-1.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/gnupg-1.0.6-1.src.rpm
**Note: You must rebuild and install the RPM if you choose to download
and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE
THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name

Subject: [TL-Security-Announce] TLSA2001026 gtk+-1.2.8-10

_________________________________________________________________________
Turbolinux Security Announcement
Package: gtk+
Vulnerable Packages: All Turbolinux versions previous to 1.2.8-6
Date: 06/06/2001 5:00 PDT
Affected Turbolinux platforms: TL 6.1 Workstation,
All Turbolinux versions
6.0.5 and earlier
Turbolinux Advisory ID#: TLSA2001026

_________________________________________________________________________
A security hole has been discovered in the package gtk+. Please update
this package in your installation as soon as possible.
_________________________________________________________________________
1. Problem Summary
The environment variable GTK_MODULES allows a local user to enter a
directory path to a module that may not be associated with the GTK+ tool-
kit. Hence, an attacker can create a custom module and load it using
the toolkit.
2. Impact
An attacker can elevate his privileges, overwrite system files and
execute potentially harmful code.
3. Solution
Update the package from our ftp server by running the following command:
rpm -Uvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gtk+-1.2.8-10.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gtk+-devel-1.2.8-10.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/gtk+-1.2.8-10.src.rpm
**Note: You must rebuild and install the RPM if you choose to download
and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE
THE SECURITY HOLE.
In order to rebuild the gtk+ binaries from the SRPM, be sure
you have XFree86-devel, glib(v1.2.8 or greater), and glib-devel(v1.2.8
or greater) installed on your system.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name

Subject: [TL-Security-Announce] TLSA2001027 tcpdump-3.62-1

Turbolinux Security Announcement
Package: tcpdump
Vulnerable Packages: All Turbolinux versions previous to 3.6.2-1
Date: 06/06/2001 5:00 PDT
Affected Turbolinux platforms: TL 6.1 Workstation,
All Turbolinux versions

Turbolinux Advisory ID#: TLSA2001027

_________________________________________________________________________
A security hole has been discovered in the package tcpdump. Please update
this package in your installation as soon as possible.
_________________________________________________________________________
1. Problem Summary
Remote buffer overflows were discovered that would enable a remote
attack of a local tcpdump process. Intrusion detection using tcpdump
would be rendered useless since the attack stops all network activity
on the system. This update also addresses the vulnerability in the
decoding of AFS ACL packets, allowing a remote attacker to run arbitrary
code on the local system as user root.
2. Solution
Update the package from our ftp server by running the following command:
rpm -Uvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/tcpdump-3.6.2-1.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/tcpdump-3.6.2-1.src.rpm
**Note: You must rebuild and install the RPM if you choose to download
and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE
THE SECURITY HOLE.
Please verify the MD5 checksums of the updates before you install:
MD5 sum Package Name
