Summary

A vulnerability was discovered in oVirt 4.1.x before 4.1.9, where the combination of Enable Discard and Wipe After Delete flags for VM disks managed by oVirt, could cause a disk to be incompletely zeroed when removed from a VM. If the same storage blocks happen to be later allocated to a new disk attached to another VM, potentially sensitive data could be revealed to privileged users of that VM.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Windows ::DATA Alternate Data Stream
    An attacker exploits the functionality of Microsoft NTFS Alternate Data Streams (ADS) to undermine system security. ADS allows multiple "files" to be stored in one directory entry referenced as filename:streamname. One or more alternate data streams may be stored in any file or directory. Normal Microsoft utilities do not show the presence of an ADS stream attached to a file. The additional space for the ADS is not recorded in the displayed file size. The additional space for ADS is accounted for in the used space on the volume. An ADS can be any type of file. ADS are copied by standard Microsoft utilities between NTFS volumes. ADS can be used by an attacker or intruder to hide tools, scripts, and data from detection by normal system utilities. Many anti-virus programs do not check for or scan ADS. Windows Vista does have a switch (-R) on the command line DIR command that will display alternate streams.
