Apple yesterday released a huge Safari update that fixes 16 vulnerabilities – six for Windows versions and ten for Mac OS X and Windows. The update, Safari 4.0.5, makes fixes in Tiger, Leopard, Snow Leopard and Windows versions. This is probably pretty significant. In November, the TheInquirer.net of the UK carried a piece about browser vulnerabilities that rated Firefox and Safari as the ones with the most vulnerabilities: ...
Hot on the heels of the Patch Tuesday announcements yesterday, came the announcement of a new zero-day in Internet Explorer (CVE-2010-0806). Whilst checking through some URLs supposedly serving up malicious code to exploit this vulnerability, I noticed a link to some spam runs from earlier in the week. On March 8th SophosLabs saw spam messages attempting to trick the recipient into visiting rogue web pages. Messages used at least two social engineering tricks to lure victims into clicking the malicious link. ...
Exploit code for the the zero-day vulnerability in Internet Explorer has been added to the Metasploit framework. According to an email HD Moore wrote to ZDNet’s Ryan Naraine, the exploit works quite reliable – successful 50% of the times on Windows XP with SP2 and SP3 with IE7 and deactivated Data Execution Prevention (DEP). The security hole got reported yesterday on Microsoft’s March 2010 Patch Tuesday. Drive-by-Download-Exploits are likely to appear now as the Metasploit framework is open source and the exploit can now be abused even by script kiddies. Time to change the default browser – Microsoft just released a new browser choice screen which allows for exactly that!
Here’s a new vector: exploiting a Windows vulnerability through an Internet Explorer help menu Visual Basic script: “get ‘em to hit F1 and you own ‘em.” Microsoft is warning of a VBScript vulnerability in Internet Explorer (on Win2K, XP and Server03) that could be used to run malicious code. A malicious operator could create a web site that displays a specially crafted dialog box and prompts a victim to press the F1 key (help menu.) The exploit could then execute malicious code on a victim machine. (Windows versions that are not vulnerable are: Vista, Win7, Server08 R2 and Server08.) ...
Evgeny Legerov, founder of Intevydis in Moscow, has created an exploit that hits a previously unknown heap-corruption vulnerability in the Firefox browser. The code isn’t readily available though, since he’s put it in a module to the automated exploitation system he sells (reportedly at a considerable price.) Legerov has not provided information on the vulnerability to Mozilla. The Intevydis site says: “Exploitation frameworks are not new on the market, but only we may offer you hundreds of CANVAS modules for unpatched and unknown vulnerabilities in highly popular software products.” ...
First, make a note: after Adobe updates, restart your machine immediately to remove the Adobe Download Manger – it can be a vector for malcode. Now, back to our story. Aviv Raff has discovered a vulnerability with Adobe’s web site in combination with its Download Manager, an ActiveX script that is used to download updates for Reader and Flash. After a Reader or Flash update the download manager remains running on a user’s machine until it is rebooted. Malicious operators could exploit it to download their code of choice. ...
Adobe has published a security bulletin about security vulnerabilities in Adobe Flash Player. In all versions up to the recent 10.0.42.34 Flash objects could evade the Sandbox which would allow for unauthorized cross domain requests. The vulnerability is rated critical. The updated version 10.0.45.2 as well of a fixed build of Adobe AIR 1.5.3.1930 is available in the flash download center and the air download center, respectively. Users should apply the update ASAP and administrators in companies should roll the fixed software out soon, too. ...
Microsoft has announced in Advisory (980088) that there has been a publicly disclosed vulnerability in Internet Explorer, versions 5 through 8. Users not running Internet Explorer in Protected Mode are at risk of having information, in files with predictable names, accessed by attackers. This vulnerability cannot be exploited to execute remote code or used for a denial-of-service attack. The largest group of users at risk are Windows XP users running IE without Protected Mode enabled. Internet Explorer on Vista and Windows 7 has Protected Mode enabled by default. ...
Early this afternoon Microsoft released an out-of-band security bulletin patching the vulnerabilities in Internet Explorer. The fix has been at the top of the news since the vulnerabilities it treats are believed to have led to the compromise of Google and about 30 other companies last week in what has been called the “Aurora” attack. The governments of France and Germany suggested that Internet users switch to a different browser until the vulnerability was fixed. ...
Now here’s an interesting turn of events. In the middle of all the attention to the “Operation Aurora” attacks, we’re now seeing new targeted attacks that are using this very event as the lure to get the targets to open a malicious attachment! Here’s the email we saw: The attachment Chinese cyberattack.pdf (md5: 238ecf8c0aee8bfd216cf3cad5d82448) is a PDF file which exploits the CVE-2009-4324 vulnerability in Adobe Reader (again, this is the one which was patched last week). ...
We just blogged about a highly targeted attack against military contractors. Now we saw one against the intelligence sector. This attack was done with a PDF file. Again. It was targetting the CVE-2009-4324 vulnerability. Again. When opened, the PDF file (md5: c3079303562d4672d6c3810f91235d9b) looked like this: What really happens in the background? Just like last time, the exploit code drops a backdoor in a file called Updater.exe (md5: 02420bb8fd8258f8afd4e01029b7a2b0). Now, what is the document talking about? President’s day? DNI Information Sharing Environment? We don’t know, but a quick web search tells us that apparently there is going to be an Intelligence fair & expo in Germany next month. ...
Adobe is currently investigating a new security hole in Reader and Acrobat. Cybercriminals are currently spamming emails with prepared documents which lead to an infection of the computer with malware. The PDF document abuses a buffer overflow in a new place within the Adobe programs. There is a JavaScript object included in the PDF which checks the Reader Version – the exploit works with Adobe Reader starting at version 8. The code it injects downloads malware which it stores in the file “winver32.exe” in the Windows directory. This file drops 3 further files which Avira detects as BDS/Ientlcp.A, TR/Agent.faa and TR/Agent.HO. ...
