Subject: [slackware-security] buffer overflow in sudo fixed
Date: Sun, 25 Feb 2001 12:03:42 -0800 (PST)
Sudo 1.6.3p6 is now available for Slackware 7.1 and Slackware -current.
This release fixes a known buffer overflow, which could be used by
malicious users to compromise parts of the system.  If you rely on Sudo
and use one of the above versions of Slackware, it is recommended that you
upgrade to the new sudo.tgz package for the version you're running.

Detailed information about Sudo can be obtained from the official web
site:

   http://www.courtesan.com/sudo/


 ===================================
 sudo 1.6.3p6 AVAILABLE - (sudo.tgz)
 ===================================

  A buffer overflow exists in the version of Sudo in Slackware 7.1 and
  -current.  Upgrading to sudo 1.6.3p6 addresses this problem.  Packages
  available:

     For Slackware -current:
     ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/ap1/sudo.tgz

     For Slackware 7.1:
     ftp://ftp.slackware.com/pub/slackware/slackware-7.1/patches/packages/sudo.tgz

  For verification purposes, we provide the following checksums:

     For Slackware -current:
        16-bit "sum" checksum:
        06790   118   sudo.tgz

        128-bit MD5 message digest:
        54eb7f61b7e7ef17a204af6369218d7d  sudo.tgz

     For Slackware 7.1:
        16-bit "sum" checksum:
        02323   118   sudo.tgz

        128-bit MD5 message digest:
        8e5453142a9beab02384d26a323273eb  sudo.tgz


  INSTALLATION INSTRUCTIONS FOR THE sudo.tgz PACKAGE:
  ---------------------------------------------------
  Make sure that no one is running sudo.  Backup any configuration files
  for sudo, then run this command as root:

         # upgradepkg sudo.tgz

  Thew version will be installed on the system and the old one will be
  removed.


Remember, it's also a good idea to backup configuration files before
upgrading packages.
