                     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

These packages are GPG signed by Turbolinux for security. Our key
is available here:

To verify a package, use the following command:

 rpm --checksig name_of_rpm

To examine only the md5sum, use the following command:

 md5sum name_of_rpm

**Note: Checking GPG keys requires RPM 3.0 or higher.

_________________________________________________________________________

                     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

_________________________________________________________________________

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

_________________________________________________________________________

                     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,

_________________________________________________________________________

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
