Mandrake Linux security advisory: sudo

Mandrake: “A problem was discovered by fc, with further research by Global
InterSec, in the sudo program with the password prompt parameter
(-p). Sudo can be tricked into allocating less memory than it should
for the prompt and in certain conditions it is possible to exploit this
flaw to corrupt the heap in such a way that could be used to execute
arbitary commands. Because sudo is generally suid root, this can lead
to an elevation of privilege for local users.”

To upgrade automatically, use MandrakeUpdate.  The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one 
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".  A list of
FTP mirrors can be obtained from:

  http://www.mandrakesecure.net/en/ftp.php

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package.  You can do this with the command:

  rpm --checksig <filename>

All packages are signed by MandrakeSoft for security.  You can obtain
the GPG public key of the Mandrake Linux Security Team from:

                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           imlib
Advisory ID:            MDKSA-2002:028
Date:                   April 25th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1
______________________________________________________________________

Problem Description:

 Previous versions of imlib, prior to 1.9.13, would fall back to the
 NetPBM library which is not suitable for loading untrusted images due
 to various problem in it's code.  The new imlib also fixes some
 problems with arguments passed to malloc().  These problems could allow
 attackers to construct images that could cause crashes or, potentially,
 the execution of arbitrary code when said images are loaded by a viewer
 that uses imlib.  

 Thanks to Alan Cox and Al Viro for discovering the problems.

Business 2.0: Buying industrial-strength tech on the cheap

Business 2.0: “Five years ago, if you had proposed running some of your company’s most critical applications on an operating system originally developed by a longhaired Finnish teenager and given away for free, your IT manager would have laughed you out of his office. That has changed, though, as Linux has become more versatile and powerful (though it’s still cheap). In fact, a new version of Linux is suitable for just about anything your company wants to throw at it.” You can read more of this article here.

Linux Weekly News for April 25, 2002

Linux Weekly News for April 25 is out. AbiWord 1.0, the CASPER project and a good bye to Best Linux are among the subjects covered in this issue.

KOffice 1.2beta1 released

Dre writes, “The dot is running a story saying KOffice 1.2beta1 has been released. According to the site, ‘The highlights of this release are WYSIWYG in KWord, KPresenter and formula objects, much
enhanced scriptability via DCOP, and a number of new and enhanced filters, including an XSLT framework for mapping between
different XML office formats.’ You can read the full announcement here.”

Apache 2.0 – Still not a contender?

adequacy.org writes “Fresh on the heels of Microsoft’s revealed plans for Windows .NET,
the Apache Project has released their own major upgrade of their server
software, named Apache 2.0. For those of you in the dark, “Apache” is
actually an Open Sores implementation of the
Microsoft HyperText
Movement Language Protocol (HTML). Today’s release will inevitably lead to a gold
rush of piracy of Apache’s sauce codes as dozens of Lunix
and *BSD fans around the world flock to the underground FTP servers to download
them.”

Microsoft, SuSE: AMD’s Opteron to be supported

The Register reports that “Advanced Micro Devices Inc yesterday unveiled the AMD Opteron, the long-touted ‘Hammer’ or ‘SledgeHammer’ 64-bit server processor, and said it has won crucial operating system support from Microsoft… In addition, SuSE Linux AG said in February it has submitted code to the Linux kernel that will allow Hammer-based boxes to run the open-source operating system. AMD expects the changes to be incorporated into Linux’s retail operating systems based on the Linux kernel version 2.6 or later.”

A coder’s guide to coffee

kuro5hin.org writes “As most software and creative professionals know, coffee is an important technology for boosting mental acuity and maintaining peak on-the-job performance. But did you also know that coffee can be a damn tasty beverage? It’s true. All you need is the appropriate

amount of disrespect for the mainstream coffee industry and a desire

to enjoy a better beverage. So read on, and learn the secrets to

great coffee.”

Evaluating Mozilla 1.0 Candidate 1

From LinuxPlanet: “Mozilla 1.0 looks promising from the standpoint of speed and ease of use. Not a whole lot has changed as far as the user interface goes. It should be noted that this beta version had some menu items on the task bar that were specifically geared for debugging and developers. I thought that was a nice touch and shows commitment to a quality product. Also, the Mozilla team is constantly updating their web site with new information, regarding recent builds, news and bug reports.”

Microsoft: How to catch a Linux migrator

From eWeek: “Microsoft Corp. is ratcheting up efforts to catch companies migrating from Unix to Linux before they make the switch.
As part of the effort, the Redmond, Wash., software giant has moved Doug Miller, current director of competitive strategy in the Windows division, to the new role of director of Unix migration strategy. In addition, Microsoft is also on track to release, before the end of June, its Services for Unix 3.0 product — the next-version software that allows greater operability between existing Unix-based enterprise systems and Windows on both the server and desktop.”
