Priority
Description
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.
Ubuntu-Description
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.
Notes
tyhicksRequires a malicious XFS filesystem image be mounted.
