Description Agostino Sarubbo gentoo-dev 2014-02-11 08:55:23 UTC
From ${URL} :

Murray McAllister from Red Hat Security Response Team discovered that rc 
creates temporary files in an insecure way:

$ strace -o '| grep /tmp' ./test-heredoc
open("/tmp/here217f.0000", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 5
open("/tmp/here217f.0000", O_RDONLY|O_LARGEFILE) = 5
unlink("/tmp/here217f.0000")            = 0

As you can see, the filenames are easily predictable, and the O_EXCL 
flag is missing.

@maintainer(s): since the package has never been marked as stable, we don't need to stabilize it. After the bump, please remove the affected versions from the tree.

Dead upstream and unpatched security vulnerability.
