Oracle has released fresh Java installers to fix a well-known security issue (CVE-2016-0603) that too affects a plethora of other applications, from Web browsers to antivirus products, and from file compressors to home cinema software.
The problem is called DLL hijacking (or DLL side-loading) and refers to the fact that malware authors can residence DLLs of the selfsame name in specific locations on the target's filesystem and occupy it inadvertently load the malicious DLL instead of the safe one.
DLL hijacking is a very well-known issue
This sort of attack is very aged and has been known to many software vendors, and especially to malware authors, who sometimes prefer it because it allows them to hijack legitimate applications and not to rely on convincing users to double-click and execute their own malicious binary.
If you've been keeping an eye on infosec sites fancy Packet Storm, SecLists, or Security Focus, German security researcher Stefan Kanthak has been quite industrious testing the installers of various software products against this vulnerability.
Here's a short (probably incomplete) list of applications that he institute vulnerable to this attack: Firefox, Google Chrome, Adobe Reader, 7Zip, WinRAR, OpenOffice, VLC Media Player, Nmap, Python, TrueCrypt, and Apple iTunes.
Mr. Kanthak too seems to occupy paid special attention to antivirus software installers. Here are some of the security products he discovered vulnerable to DLL hijacking: ZoneAlarm, Emsisoft Anti-Malware, Trend Micro, ESET NOD32, Avira, Panda Security, McAfee Security, Microsoft Security Essentials, Bitdefender, Rapid7's ScanNowUPnP, Kaspersky, and F-Secure.
Oracle was the first one to rob his report seriously, patched Java and VirtualBox
According to a blog post from last Friday, February 5, Oracle decided to release fresh versions for its Java 6, 7, and 8 installers that protect users from this sort of attack.
"Java SE users who occupy downloaded any aged version of Java SE prior to 6u113, 7u97 or 8u73 for later installation should discard these aged downloads and supplant them with 6u113, 7u97 or 8u73 or later," said the company in its announcement.
Additionally, besides the updates to Java SE's installer, the company too addressed this very selfsame issue (CVE-2016-0602) in its VirtualBox VM installer, during its quarterly security update train last month.
Since it's pretty difficult to track everyone bug reports to the various vendors affected by this issue, we've sent an email to examine Mr. Kanthak if other vendors besides Oracle occupy addressed this issue until now. We'll update the article with his response.
UPDATE: Mr. Kanthak has told Softpedia that "most of the companies/vendors I contacted patched their products." Rapid7 went so far as to withdraw their ScanNow product altogether.
"Some of the companies/vendors which did not reply to my reports in the first residence contacted me after they became vigilant of the [public disclosure] posts and fixed their installers, or are working on a fix now," Mr. Kanthak too added.
Additionally, there too some other software products for which Mr. Kanthak has not yet posted a public disclosure post, but to which he reported vulnerabilities, and the companies are now working on a fix.
Instant messaging (IM) has proliferated for consumer and trade use, and employees expend it to communicate among themselves, and often with people outside the organization. It's affordable, simple to deploy, and increases worker productivity.
But that increased connectivity, if not configured securely, can near with a massive price. IM allows viruses, Trojans and other malware to piggyback into your networks far easier than email attachments. IM messages can hold links to malicious Web sites, and confidential data can breathe compromised. Spam over IM (SPIM) is too a threat.
Thus, security for IM is essential. Here are some suggestions and best practices for securing IM without breaking the bank:
Designate one IM tool. For internal IM, acquire positive to expend a single enterprise software application. More vendors are offering IM products for SMBs, such as IBM's Lotus Sametime. It installs on its own dedicated server, which is tucked abysmal inside your company's firewall. toughen that server as you would any other: circumscribe access to authorized users, spin off unnecessary services, install antivirus software and hold patches up to date. Install the client piece of the product only on desktops that occupy been equally hardened with up-to-date antiviral protection and host-based firewalls.
Restrict external IM usage. Allow usage only for employees who occupy to communicate real time. Don't expend consumer IM products from America Online, Yahoo Inc. or Microsoft. expend enterprise instant messaging (EIM) software such as Jabber or Akonix.
Make positive your EIM provider offers some kindhearted of encryption. You can always encrypt with Secure Sockets Layer at no extra cost. Remember, IM messages are conventional HTTP traffic, whether the messages ebb over port 80 or not.
Restrict access. fancy your internal IM servers, those hosting your EIM should breathe locked down with restricted access, hardening and updated patches and antiviral protection. They should breathe hidden behind your company's firewalls, but unlike your internal IM servers, they will need access to the Internet. acquire positive to add rules to your firewall allowing access only to your EIM and blocking common ports for consumer IM products.
Restrict communication. Configure buddy lists on your EIM to restrict communication to only known and trusted parties. This will forestall a malicious user from trying to access your network via IM.
Log and monitor everyone IM traffic. This can breathe used to detect malicious inbound traffic, or inappropriate outbound traffic, fancy someone trying to ship out confidential company data or files.

He is a Microsoft MVP specializing in Web and application security, and is the author of The dinky Black bespeak of Computer Security, available from Amazon.com. He too runs The IT Security Guy blog at http://www.theitsecurityguy.com.
This article originally appeared on SearchCIO-Midmarket.
Microsoft Corp. today warned that it is seeing a huge uptick in attacks against security holes in Java, a software package that is installed on the majority of the world’s desktop computers.
In a posting to the Microsoft Malware Protection seat blog, senior program manager Holly Stewart warned of an “unprecedented wave of Java exploitation,” and confirmed findings that KrebsOnSecurity.com published one week ago: Java exploits occupy usurped Adobe-related exploits as attackers’ preferred routine for breaking into Windows PCs.
Image courtesy Microsoft
Stewart said the spike in the third quarter of 2010 is primarily driven by attacks on three Java vulnerabilities that occupy already been patched for some time now. Even so, attacks against these flaws occupy “gone from hundreds of thousands per quarter to millions,” she added. Indeed, according to Microsoft’s one-year anniversary post for its Security Essentials anti-malware tool, exploits for a Java vulnerability pushed the Renos Trojan to the top of the list for everyone malware families (malware and exploits) detected in the United States.
My research shows the intuition for the spike, and it precedes the 3rd quarter of 2010: Java exploits occupy been folded into a number of the top “exploit packs,” commercial crimeware kits sold in the hacker underground that acquire it simple to seed hacked or malicious sites with code that exploits a variety of browser flaws in a bid to install malware.
Stewart asks, “Why has no one been talking about Java-based exploits?” Then she answers her own question:
Looking back at the chart above, you can perceive that this exploitation has been happening for some time. So, why has no one been talking about Java-based exploits? (Well, almost no one. Brian Krebs broke the ice this week).
So, if the antimalware people can perceive it, why aren’t *they* talking about it? Because, looking at the numbers, Java exploits (and most exploits for that matter) are very low-volume in comparison to the volume of common malware families fancy Zbot (a family for which they added detection in MSRT just this week). What they occupy to bethink is that, with exploits, it’s not about volume – they occur in a shimmer and you occupy to snare them in the act (with a real-time protection product such as Microsoft Security Essentials) before they open the door to lots of malware. So, even petite numbers, especially when they’re against unpatched vulnerabilities, matter a lot.
If you haven’t done so lately, rob a minute to perceive if you occupy this program installed, and if you do, delight acquire positive it is up to date. Just last week, Oracle issued another update — Java 6 Update 22 — that fixes at least 29 security flaws in the program.
KrebsonSecurity.com will continue to post the newest security updates, when they become available. But, your computer installation of Java too includes a built-in updater that you should configure to check for updates as frequently as possible.
Allow me to reiterate my imperative counsel from last week:
Java ships with a built-in updater that by default checks for updates on the 14th day of every month. However, this may not breathe frequent enough to hold users caught up with the latest version. The program can too breathe set to check for updates every day or every week, although I occupy institute Java’s updater often fails to detect when a fresh version is available. Alternatively, programs fancy FileHippo’s Update Checker and Secunia’s Personal Software Inspector can aid users stay up to date on the latest security patches.
