CVE-2011-4077

Status Candidate

Overview

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.

Red Hat Security Advisory 2012-0350-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A buffer overflow flaw was found in the way the Linux kernel's XFS file system implementation handled links with overly long path names. A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by mounting a specially-crafted disk.

Red Hat Security Advisory 2012-0333-01 - Updates have been made to the Linux kernel. SG_IO ioctl SCSI requests on partitions or LVM volumes could be passed to the underlying block device, allowing a privileged user to bypass restrictions and gain read and write access to the entire block device. A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. A local, unprivileged user could use a flaw in the Performance Events implementation to cause a denial of service. Various other issues have also been addressed.
