{"id":"DEBIAN-CVE-2009-0654","details":"Tor 0.2.0.28, and probably 0.2.0.34 and earlier, allows remote attackers, with control of an entry router and an exit router, to confirm that a sender and receiver are communicating via vectors involving (1) replaying, (2) modifying, (3) inserting, or (4) deleting a single cell, and then observing cell recognition errors at the exit router.  NOTE: the vendor disputes the significance of this issue, noting that the product's design \"accepted end-to-end correlation as an attack that is too expensive to solve.\"","modified":"2026-09-22T16:47:35.304257305Z","published":"2009-02-20T19:30:00.313Z","upstream":["CVE-2009-0654"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2009-0654"}],"affected":[{"package":{"name":"tor","ecosystem":"Debian:12","purl":"pkg:deb/debian/tor?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4.7.13-1","0.4.7.16-1","0.4.8.10-1","0.4.8.10-1~bpo11+1","0.4.8.10-1~bpo12+1","0.4.8.11-1","0.4.8.11-1~bpo11+1","0.4.8.11-1~bpo12+1","0.4.8.12-1","0.4.8.12-1.1","0.4.8.12-1~bpo11+1","0.4.8.12-1~bpo12+1","0.4.8.13-1","0.4.8.13-2","0.4.8.13-2~bpo12+1","0.4.8.14-1","0.4.8.14-1~bpo12+1","0.4.8.16-1","0.4.8.21-1","0.4.8.21-1~bpo12+1","0.4.8.21-1~bpo13+1","0.4.8.21-1~bpo13+2","0.4.8.22-1","0.4.8.22-1~bpo12+1","0.4.8.22-1~bpo13+1","0.4.8.4-2","0.4.8.5-1","0.4.8.6-1","0.4.8.7-1","0.4.8.8-1","0.4.8.9-1","0.4.8.9-1~bpo11+1","0.4.8.9-1~bpo12+1","0.4.9.11-0+deb12u1","0.4.9.11-1","0.4.9.11-1~bpo13+1","0.4.9.12-2","0.4.9.12-3","0.4.9.12-4","0.4.9.5-1","0.4.9.5-2","0.4.9.5-2~bpo12+1","0.4.9.5-2~bpo13+1","0.4.9.6-0+deb12u1","0.4.9.6-1","0.4.9.6-1~bpo12+1","0.4.9.6-1~bpo13+1","0.4.9.8-0+deb12u1","0.4.9.8-1","0.4.9.8-1~bpo12+1","0.4.9.8-1~bpo13+1","0.4.9.9-1","0.4.9.9-1~bpo13+1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2009-0654.json"}},{"package":{"name":"tor","ecosystem":"Debian:13","purl":"pkg:deb/debian/tor?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4.8.16-1","0.4.8.21-1","0.4.8.21-1~bpo12+1","0.4.8.21-1~bpo13+1","0.4.8.21-1~bpo13+2","0.4.8.22-1","0.4.8.22-1~bpo12+1","0.4.8.22-1~bpo13+1","0.4.9.11-0+deb13u1","0.4.9.11-1","0.4.9.11-1~bpo13+1","0.4.9.12-0+deb13u1","0.4.9.12-0+deb13u2","0.4.9.12-2","0.4.9.12-3","0.4.9.12-4","0.4.9.5-1","0.4.9.5-2","0.4.9.5-2~bpo12+1","0.4.9.5-2~bpo13+1","0.4.9.6-0+deb13u1","0.4.9.6-1","0.4.9.6-1~bpo12+1","0.4.9.6-1~bpo13+1","0.4.9.8-0+deb13u1","0.4.9.8-1","0.4.9.8-1~bpo12+1","0.4.9.8-1~bpo13+1","0.4.9.9-1","0.4.9.9-1~bpo13+1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2009-0654.json"}},{"package":{"name":"tor","ecosystem":"Debian:14","purl":"pkg:deb/debian/tor?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4.8.16-1","0.4.8.21-1","0.4.8.21-1~bpo12+1","0.4.8.21-1~bpo13+1","0.4.8.21-1~bpo13+2","0.4.8.22-1","0.4.8.22-1~bpo12+1","0.4.8.22-1~bpo13+1","0.4.9.11-1","0.4.9.11-1~bpo13+1","0.4.9.12-2","0.4.9.12-3","0.4.9.12-4","0.4.9.5-1","0.4.9.5-2","0.4.9.5-2~bpo12+1","0.4.9.5-2~bpo13+1","0.4.9.6-1","0.4.9.6-1~bpo12+1","0.4.9.6-1~bpo13+1","0.4.9.8-1","0.4.9.8-1~bpo12+1","0.4.9.8-1~bpo13+1","0.4.9.9-1","0.4.9.9-1~bpo13+1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2009-0654.json"}}],"schema_version":"1.9.0"}
