vzkernel before 042stab080.2 in the OpenVZ modification for the Linux kernel 2.6.32 does not initialize certain length variables, which allows local users to obtain sensitive information from kernel stack memory via (1) a crafted ploop driver ioctl call, related to the ploop_getdevice_ioc function in drivers/block/ploop/dev.c, or (2) a crafted quotactl system call, related to the compat_quotactl function in fs/quota/quota.c.

Security readout for executives and security teams

CVE-2013-2239 is a local information-disclosure flaw in OpenVZ’s modified Linux 2.6.32 kernel. A local user could trigger affected kernel paths and receive uninitialized kernel stack data, potentially exposing sensitive memory. The sources describe local disclosure, not remote code execution. Exposure is most likely on legacy OpenVZ hosts running the modified Linux 2.6.32 vzkernel before 042stab080.2, including downstream packages tracked by Debian or Gentoo. Systems not using OpenVZ vzkernel are not shown as affected in the bundle. Prioritize remediation for shared hosting, multi-tenant OpenVZ, or systems with untrusted local users. For isolated legacy hosts with tightly controlled access, handle through normal kernel maintenance, but do not leave unsupported OpenVZ kernels untracked. Mitigation focus: Upgrade OpenVZ vzkernel to 042stab080.2 or later where applicable.; Apply relevant distribution security updates, including Debian DSA-2766 where applicable.; Check OpenVZ, Debian, and Gentoo guidance for package-specific fixed versions..
