Vulnerability Name:

CVE-2009-4411 (CCN-55004)

Assigned:2009-06-22
Published:2009-06-22
Updated:2017-08-17
Summary:The (1) setfacl and (2) getfacl commands in XFS acl 2.2.47, when running in recursive (-R) mode, follow symbolic links even when the --physical (aka -P) or -L option is specified, which might allow local users to modify the ACL for arbitrary files or directories via a symlink attack.
