Subject: coreutils: chown --dereference changes gid when it shouldn't
Package: coreutils
Version: 5.2.1-2
Severity: normal
*** Please type your report below this line ***
If one uses chown with --dereference to only set the owner, it incorrectly
may change the group as well. It will set the owner of the pointed-to item
to the owner requested, but then also change the group to the group of the
symlink.
This happens because chown reads owner and group from the filename passed,
but then, if --dereference is in effect, runs the chown against the file
pointed to. The offending code is in src/chown-core.c, approximately lines
211 to 225, and also in the chown_files function. In dereference mode, it
needs to not only apply the changes to the dereferenced file, but also to
read the current ownership from the dereferenced file.
