CVE-2010-2798 (aura_communication_manager, aura_presence_services, aura_session_manager, aura_system_manager, aura_system_platform, debian_linux, esx, iq, linux_enterprise_high_availability_extension, linux_kernel, opensuse, suse_linux_enterprise_desktop, suse_linux_enterprise_server, ubuntu_linux, voice_portal)

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.
