Overview

tar vulnerability


Details

Teemu Salmela discovered that tar still handled the deprecated
GNUTYPE_NAMES record type. This record type could be used to create
symlinks that would be followed while unpacking a tar archive. If a
user or an automated system were tricked into unpacking a specially
crafted tar file, arbitrary files could be overwritten with user
privileges.
