Vulnerability Title
Libnbd: libnbd: arbitrary code execution via ssh argument injection through a malicious uri
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). This vulnerability arises because non-standard hostnames starting with '-o' are incorrectly interpreted as arguments to the Secure Shell (SSH) process, rather than as hostnames. This could lead to arbitrary code execution with the privileges of the user running libnbd.
