VMware has released a slew of patches that fix vulnerabilities in a number of its products, including vCenter Server, vCenter Server Appliance, vSphere Update Manager, ESX and ESXi. Some of the flaws can lead to authentication bypass or denial of service on affected products. The most serious vulnerability is a bug in vCenter Server 5.0 and[…]
Virtualization software maker VMware issued an update last Thursday resolving a virtual machine communication interface (VMCI) vulnerability in its ESX Server, Workstation, Fusion and View products that could lead to a privilege escalation if unpatched.According to the VMware security advisory, a local attacker could potentially exploit a control code handling vulnerability in vmci.sys in order to tamper with memory allocation in the VMCI code and eventually obtain elevated privileges on Windows-based hosts and guest operating systems.
For the third time this year, VMware ESX source code has been posted online. A hacker known as Stun claiming to be affiliated with Anonymous tweeted a link to a torrent site hosting the stolen VMkernel source code. VMware director of platform security Iain Mulholland acknowledged the breach on Sunday and confirmed the source code, dating from 1998-2004, is related to code posted in April and May.
Details of a dangerous virtual machine escape exploit were revealed Wednesday by French research outfit VUPEN Security. The attack exploits a recently reported vulnerability in Xen hypervisors and allows an attacker within a guest virtual machine to escape to the host and execute code.
With the deluge of malware and advanced attacks continuing unabated, security approaches that sandbox applications or isolate processes are garnering increased attention. Researcher Joanna Rutkowska and Invisible Things Lab were the latest to go in that direction with the official release on Tuesday of the Qubes operating system.
The Windows version of the Crisis Trojan is able to sneak onto VMware implementations, making it possibly the first malware to target such virtual machines. It also has found a way to spread to Windows Mobile devices.
The Honeynet Project launched a new project Thursday that is designed to snare malware that spreads by infecting removable USB (universal serial bus) storage drives, citing the increased reliance of malicious programs on portable drives to move from computer to computer.
Right on cue this week, the anarchic hacking collective Anonymous stepped up and grabbed the story line away from the lions of the IT security industry.With the annual RSA Conference set to begin, the whistle blowing site Wikileaks released the first of some five million e-mail messages stolen from the security intelligence firm Stratfor. Ever sensitive to the fickle attention of the media, Anonymous inserted itself into the story, claiming responsibility for leaking the data and pointing a finger of blame at Stratfor and its media, private and public sector customers, which Anonymous accuses of spying and other dark offenses.
By Rob LemosThere are a lot of good reasons to have remote-access software installed on a business network: It might be there to allow a remote administrator to manage a database; or to give a third-party point-of-sale management firm to apply patches; or even to allow a PBX vendor access to the server managing their client’s voice-over-IP lines. Unfortunately, through poor configuration, bad passwords or vulnerabilities, the software is also allowing attackers in to steal data and is becoming an increasingly popular attack vector.
