CVE-2012-3447
virt/disk/api.py in OpenStack Compute (Nova) 2012.1.x before 2012.1.2 and Folsom before Folsom-3 allows remote authenticated users to overwrite arbitrary files via a symlink attack on a file in an image that uses a symlink that is only readable by root.
Does this matter?
Lower severity and a low EPSS score (1.93%). Track it; it rarely justifies an emergency change on its own.
