Description

census reported a directory traversal vulnerability in src/torrent_info.cpp that can be triggered via .torrent files.

Impact

A remote attacker could entice a user or automated system using Rasterbar libtorrent to load a specially crafted BitTorrent file to create or overwrite arbitrary files using dot dot sequences in filenames.

Workaround

There is no known workaround at this time.

Resolution

All Rasterbar libtorrent users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-libs/rb_libtorrent-0.13-r1"

All Deluge users should upgrade to the latest version:


    # emerge --sync
