Description Tomas Hoger 2007-08-13 10:23:06 EDT
Directory traversal vulnerability was discovered in GNU tar.  Vulnerability can
be exploited by specially crafted tar archive to overwrite arbitrary file
writable by user running tar.  Problem occurs in contains_dot_dot function,
which does not properly check names of directory symlinks.


Red Hat would like to thank Dmitry V. Levin for reporting this issue.
