{"id":"DEBIAN-CVE-2012-6706","details":"A VMSF_DELTA memory corruption was discovered in unrar before 5.5.5, as used in Sophos Anti-Virus Threat Detection Engine before 3.37.2 and other products, that can lead to arbitrary code execution. An integer overflow can be caused in DataSize+CurChannel. The result is a negative value of the \"DestPos\" variable, which allows the attacker to write out of bounds when setting Mem[DestPos].","modified":"2026-09-05T07:00:48.309252255Z","published":"2017-06-22T13:29:00.173Z","upstream":["CVE-2012-6706"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2012-6706"}],"affected":[{"package":{"name":"libclamunrar","ecosystem":"Debian:12","purl":"pkg:deb/debian/libclamunrar?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.99-4"}]}],"versions":["0.95.1-1","0.95.2-1","0.95.3-1","0.95.3-1~volatile1","0.96-1","0.96-2","0.96-2~volatile1","0.96.4-1","0.96.4-1~volatile1","0.98.1-1","0.98.5-1","0.99-1","0.99-2","0.99-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}},{"package":{"name":"libclamunrar","ecosystem":"Debian:13","purl":"pkg:deb/debian/libclamunrar?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.99-4"}]}],"versions":["0.95.1-1","0.95.2-1","0.95.3-1","0.95.3-1~volatile1","0.96-1","0.96-2","0.96-2~volatile1","0.96.4-1","0.96.4-1~volatile1","0.98.1-1","0.98.5-1","0.99-1","0.99-2","0.99-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}},{"package":{"name":"libclamunrar","ecosystem":"Debian:14","purl":"pkg:deb/debian/libclamunrar?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.99-4"}]}],"versions":["0.95.1-1","0.95.2-1","0.95.3-1","0.95.3-1~volatile1","0.96-1","0.96-2","0.96-2~volatile1","0.96.4-1","0.96.4-1~volatile1","0.98.1-1","0.98.5-1","0.99-1","0.99-2","0.99-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}},{"package":{"name":"unrar-nonfree","ecosystem":"Debian:12","purl":"pkg:deb/debian/unrar-nonfree?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:5.5.5-1"}]}],"versions":["1:3.5.2-0.1","1:3.5.2-0.2","1:3.5.4-0.1","1:3.5.4-1","1:3.5.4-1.1","1:3.7.2-1","1:3.7.3-1","1:3.7.3-1.1","1:3.7.8-1","1:3.7.8-2","1:3.8.2-1","1:3.8.4-1","1:3.8.5-1","1:3.8.5-2","1:3.9.10-1","1:3.9.3-1","1:3.9.5-1","1:3.9.6-1","1:3.9.7-1","1:3.9.9-1","1:4.0.2-1","1:4.0.3-1","1:4.1.4-1","1:4.2.4-0.1","1:4.2.4-0.2","1:4.2.4-0.3","1:5.0.10-1","1:5.2.5-1","1:5.2.7-0.1","1:5.3.2-1","1:5.4.5-1","3.3.6-2","3.3.6-2.0.1","3.4.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}},{"package":{"name":"unrar-nonfree","ecosystem":"Debian:13","purl":"pkg:deb/debian/unrar-nonfree?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:5.5.5-1"}]}],"versions":["1:3.5.2-0.1","1:3.5.2-0.2","1:3.5.4-0.1","1:3.5.4-1","1:3.5.4-1.1","1:3.7.2-1","1:3.7.3-1","1:3.7.3-1.1","1:3.7.8-1","1:3.7.8-2","1:3.8.2-1","1:3.8.4-1","1:3.8.5-1","1:3.8.5-2","1:3.9.10-1","1:3.9.3-1","1:3.9.5-1","1:3.9.6-1","1:3.9.7-1","1:3.9.9-1","1:4.0.2-1","1:4.0.3-1","1:4.1.4-1","1:4.2.4-0.1","1:4.2.4-0.2","1:4.2.4-0.3","1:5.0.10-1","1:5.2.5-1","1:5.2.7-0.1","1:5.3.2-1","1:5.4.5-1","3.3.6-2","3.3.6-2.0.1","3.4.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}},{"package":{"name":"unrar-nonfree","ecosystem":"Debian:14","purl":"pkg:deb/debian/unrar-nonfree?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:5.5.5-1"}]}],"versions":["1:3.5.2-0.1","1:3.5.2-0.2","1:3.5.4-0.1","1:3.5.4-1","1:3.5.4-1.1","1:3.7.2-1","1:3.7.3-1","1:3.7.3-1.1","1:3.7.8-1","1:3.7.8-2","1:3.8.2-1","1:3.8.4-1","1:3.8.5-1","1:3.8.5-2","1:3.9.10-1","1:3.9.3-1","1:3.9.5-1","1:3.9.6-1","1:3.9.7-1","1:3.9.9-1","1:4.0.2-1","1:4.0.3-1","1:4.1.4-1","1:4.2.4-0.1","1:4.2.4-0.2","1:4.2.4-0.3","1:5.0.10-1","1:5.2.5-1","1:5.2.7-0.1","1:5.3.2-1","1:5.4.5-1","3.3.6-2","3.3.6-2.0.1","3.4.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2012-6706.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
