CVE-2011-4077

Published: 29 October 2011

Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS in the Linux kernel 2.6, when CONFIG_XFS_DEBUG is disabled, allows local users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via an XFS image containing a symbolic link with a long pathname.

From the Ubuntu security team

A bug was discovered in the XFS filesystem's handling of pathnames. A local attacker could exploit this to crash the system, leading to a denial of service, or gain root privileges.

Priority

Low
