Unspecified vulnerability in the VirtualBox component in Oracle Virtualization 4.0, 4.1, and 4.2 allows local users to affect integrity and availability via unknown vectors related to Core. NOTE: The previous information was obtained from the January 2013 Oracle CPU. Oracle has not commented on claims from another vendor that this issue is related to an incorrect comparison in the vga_draw_text function in Devices/Graphics/DevVGA.cpp, which can cause VirtualBox to "draw more lines than necessary."

Security readout for executives and security teams

CVE-2013-0420 is a 2013 VirtualBox flaw in Oracle Virtualization 4.0, 4.1, and 4.2. A local user on a system running affected VirtualBox could affect integrity and availability. The public record is sparse: no CVSS, CWE, or confirmed exploit detail is provided. Exposure is most likely on legacy hosts or appliances still running VirtualBox from Oracle Virtualization 4.0, 4.1, or 4.2, including old distribution packages. Modern environments are mainly at risk if unsupported VirtualBox builds remain installed. Treat this as a legacy cleanup and patch-compliance issue unless affected VirtualBox hosts are still business-critical. Urgency increases where untrusted local users can access the host or where old virtualization stacks support sensitive workloads. Mitigation focus: Identify any VirtualBox 4.0, 4.1, or 4.2 installations.; Apply Oracle or operating-system vendor VirtualBox security updates.; Retire unsupported VirtualBox versions where updates are unavailable..
