CVE-2013-6382
Description
From CVE.org
Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c.
Statement
The Red Hat Security Response Team does not consider this issue to be a security flaw due to the full root-like privileges (CAP_SYS_ADMIN) needed for successful exploitation.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
