Fedora 29 : python-paramiko (2018-ea6b328afd)

Python Paramiko versions 2.3.2 and 2.4.1 are vulnerable to an authentication bypass in paramiko/authhandler.py. A remote attacker could exploit this vulnerability in Paramiko SSH servers to execute arbitrary code. Note that applications using Paramiko only as a client such as ansible are not...

GoScanSSH Malware Targets SSH Servers, But Avoids Military and .GOV Systems

Researchers have identified a new malware family, dubbed GoScanSSH, that targets public facing SSH servers, but avoids those linked to government and military IP addresses. The malware has been in the wild since June 2017 and exhibits a number of unique characteristics, such as being written in t...

Executive Summary During a recent Incident Response IR engagement, Talos identified a new malware family that was being used to compromise SSH servers exposed to the internet. This malware, which we have named...

FreeBSD : FreeBSD -- Incorrect error handling in PAM policy parser (6e8f9003-6007-11e6-a6c3-14dae9d210b8)

The OpenPAM library searches for policy definitions in several locations. While doing so, the absence of a policy file is a soft failure handled by searching in the next location while the presence of an invalid file is a hard failure handled by returning an error to the caller. The policy parser...
