Christey" <coley@...us.mitre.org> CC: oss-security <oss-security@...ts.openwall.com> Subject: CVE Request -- Transmission v1.92 Hi Steve, vendors, Transmission upstream has recently released latest, v1.92 version:  http://trac.transmissionbt.com/wiki/Changes fixing one (potentially two) security issues: a, Fix potential buffer overflow when adding maliciously-crafted magnet links References:  http://trac.transmissionbt.com/ticket/2965  http://trac.transmissionbt.com/wiki/Changes  http://bugs.gentoo.org/show_bug.cgi?id=309831 -- b, Fix possible data corruption issue caused by data sent by bad peers during endgame (this one I am not completely sure of, but when looking at the relevant bug record:  http://trac.transmissionbt.com/ticket/1242 there is written:  http://trac.transmissionbt.com/ticket/1242#comment:1 "My theory is that for some reason Transmission will download a corrupt part from someone but not realize it until you do a manual verify. At this point T will recognize the bad part and redownload it from the same person, which just causes the problem again." so to prevent someone from successfully downloading content of some torrent file, for an attacker to should be enough to download a part of it, corrupt it and share it. Not sure about the algorithm, Transmission decides which torrent to retrieve content from, but if it is deterministic / predictable behavior / algorithm, such attack could succeed). References:  http://trac.transmissionbt.com/ticket/1242  http://trac.transmissionbt.com/ticket/1242#comment:1  http://trac.transmissionbt.com/wiki/Changes Could you allocate CVE id(s) for this / these issue(s)? Thanks && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
