Secret answers as insecure passwords

Here at LWN security headquarters, we have received hundreds of messages from readers with one crucial security question on their minds: how was Paris Hilton's T-Mobile account cracked? Well...OK...maybe we haven't received quite that many messages. But we're sure people will want to know. Turns out that OSDir has the answer. Apparently T-Mobile's site has a "secret answer" mechanism for people who forget their passwords. Ms Hilton's "secret answer" was her dog's name. Bitten again.

Wherever there is a potential security problem, there is inevitably a Bruce Schneier column warning about it. In this case, Bruce notes:

Passwords have reached the end of their useful life. Today, they only work for low-security applications. The secret question is just one manifestation of that fact.

Passwords may well be heading toward the end of their useful life, but "secret answers" are not necessarily a demonstration of that fact. Many web sites (or other interfaces requiring confirmation) go out of their way to prevent the use of insecure passwords. Some site developers put considerable effort into creating novel rules for passwords. Then they add a "secret answer" mechanism which bypasses all of that.

The real issue here, perhaps, is that an authentication interface should actually control access to the resources it protects. Back doors are never good for the security of a system, and a "secret answer" scheme is really just a form of back door. If you provide a way around your password interface, you should not be surprised if attackers use it.

New IDN Homograph Spoofing Response: IDN Will Not Be Disabled (MozillaZine)

MozillaZine reports that IDN support will not be disabled. The details of the new short term solution are available. "Darin Fisher, network supremo, has pulled it out of the bag and come up with a less drastic short-term solution to the IDN problem. It has just been checked in for all three upcoming releases. Read about it over in bug 282270, but basically IDN will still work, but all occurrences of IDN domains in the browser UI (URL bar, security info etc.) will be the punycode form. There is a pref to re-enable full IDN - set "network.IDN_show_punycode" to false. As with the previous plan, this preference will be set to true in all official builds." Meanwhile the search for a long term solution continues.

glibc: Information leak with LD_DEBUG

Package(s):glibc CVE #(s):CAN-2004-1453
Created:August 17, 2004 Updated:May 26, 2005
Description: Silvio Cesare discovered a potential information leak in glibc. It allows LD_DEBUG on SUID binaries where it should not be allowed. This has various security implications, which may be used to gain confidential information. An attacker can gain the list of symbols a SUID application uses and their locations and can then use a trojaned library taking precedence over those symbols to gain information or perform further exploitation.

libgd2: buffer overflows in PNG handling

Package(s):libgd2 CVE #(s):CAN-2004-0990 CAN-2004-0941
Created:October 29, 2004 Updated:June 28, 2006
Description: Several buffer overflows have been discovered in libgd's PNG handling functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function.

Created:February 15, 2005 Updated:March 15, 2005
Description: Michael Kerrisk noticed an insufficient permission checking in the shmctl() function. Any process was permitted to lock/unlock any System V shared memory segment that fell within the the RLIMIT_MEMLOCK limit (that is the maximum size of shared memory that unprivileged users can acquire). This allowed am unprivileged user process to unlock locked memory of other processes, thereby allowing them to be swapped out. Usually locked shared memory is used to store passphrases and other sensitive content which must not be written to the swap space (where it could be read out even after a reboot). (CAN-2005-0176)

OGAWA Hirofumi noticed that the table sizes in nls_ascii.c were incorrectly set to 128 instead of 256. This caused a buffer overflow in some cases which could be exploited to crash the kernel. (CAN-2005-177)

A race condition was found in the terminal handling of the "setsid()" function, which is used to start new process sessions. (CAN-2005-178)
