Background ========== Rasterbar libtorrent is a C++ BitTorrent implementation focusing on efficiency and scalability. Deluge is a BitTorrent client that ships a copy of libtorrent. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/rb_libtorrent < 0.13-r1 >= 0.13-r1 2 net-p2p/deluge < 1.1.9 >= 1.1.9 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- 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 -v ">=net-libs/rb_libtorrent-0.13-r1" All Deluge users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-p2p/deluge-1.1.9" References ========== [ 1 ] CVE-2009-1760 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1760 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200907-14.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
