OpenSSH Vulnerability (NEW)
*** IMPORTANT UPDATE: ***
**OpenSSH 3.7.1p2 was released on September 23rd.**
It fixes additional security problems. No details yet.
****************************
A vulnerability has been discovered in OpenSSH which also affects the recent released versions 3.7p1 and 3.7.1p1.
We highly recommend upgrading to the version 3.7.1p2 which was released this morning. The new version 3.7.1p2 fixes additional relating issues in PAM module, not covered in 3.7.1p1.
This new bug may be remotely exploited according the recent released announce: "Under a non-standard configuration, with privsep disabled". This bug may not be exploitable on some platforms (e.g. OpenBSD) but could be exploitable on others (e.g. Linux).
Currently, there is no widely available exploit.
Workaround for this new bug (also affects 3.7p1 and 3.7.1p1)
(*) Upgrade to Portable OpenSSH 3.7.1p2 or disable PAM support ("UsePam no" in sshd_config).
(*) Allow only trusted hosts to access port 22
(*) Enable the 'Privilege Separation feature. It is not clear if this will prevent the current exploit. But it is likely to make any compromise harder
at the time of this writing, no major Linux distribution released an official update.
OpenSSH is used in a number of devices sold by various vendors. Examples are Cisco and Juniper routers. We do not know at this point if these devices are vulnerable. Please contact your vendor for details.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
