CVSS v3.1
Official Description
libguestfs before 1.5.23, as used in virt-v2v, virt-inspector 1.5.3 and earlier, and possibly other products, when a raw-format disk image is used, allows local guest OS administrators to read files from the host via a crafted (1) qcow2, (2) VMDK, or (3) VDI header, related to lack of support for a disk format specifier.
Technical Analysis
CVE-2010-3851 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
