A stack-based buffer overflow flaw was found in the way Transmission, a free, lightweight BitTorrent client, performed connection acknowledgements processing. A remote attacker could issue a specially-crafted request that, when processed would lead to transmission-daemon crash.

Directory traversal vulnerability in libtransmission/metainfo.c in Transmission 1.22, 1.34, 1.75, and 1.76 allows remote attackers to overwrite arbitrary files via a .. (dot dot) in a pathname within a .torrent file.

Multiple cross-site scripting (XSS) vulnerabilities in the web client in Transmission before 2.61 allow remote attackers to inject arbitrary web script or HTML via the (1) comment, (2) created by, or (3) name field in a torrent file.

Integer overflow in the trbitfieldEnsureNthBitAlloced function in bitfield.c in Transmission before 2.84 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted peer message, which triggers an out-of-bounds write.
