Description Todd Cullum 2022-02-15 01:18:33 UTC 
In libarchive before 3.5.2, when an archive entry contains a symbolic link that has defined ACLs on Linux, on extraction the ACLs of the link target are modified. This is because the function acl_set_file() is used without a prior check if the file is not a symbolic link. On Linux ACLs on symbolic links are not supported.
