The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the \"bytes_in_use\" field should be less than the \"bytes_allocated\" field. When it is not, the parsing of the records proceeds into the wild.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tuxera/ntfs-3g","events":[{"introduced":"0"},{"fixed":"31ac7e4f0fc07beeca455eba6a8f02abd7e4d76f"}],"database_specific":{"cpe":"cpe:2.3:a:tuxera:ntfs-3g:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2021.8.22"}],"source":"CPE_RANGE"}}],"versions":["2021.8.14","2021.5.19","2017.3.23","2017.2.15","2016.2.22","2016.2.15","2015.3.14","2015.3.13","2015.3.5","2014.2.15","v2013_1_13","v2012_1_15","v2011_10_9_RC","v2011_4_12","v2011_4_11","v2011_4_10","v2011_3_28_RC","v2011_3_26","2011_3_26","N2010_10_2","N2010_8_8","N2010_7_23_RC","N2010_6_31_RC","N2010_6_30_RC","N2010_5_22","N2010_5_16","N2010_2_6","R2009_10_5_RC","N2009_10_03_104125","N2009_10_03_095644","PERMISSION_HANDLING_BASE_20070925","N1_913","N1_910_RC","N1_826","N1_810","N1_710","N1_616","N1_612_RC","N1_516","N1_417","N1_416","N1_411_RC","N1_328","N1_320_RC","N1_0","N0_20070207_RC1","N0_20070118_BETA","N0_20070116_BETA","N0_20070102_BETA","N0_20061218_BETA","N0_20061212_BETA","N2006_11_14_220946","N0_20061115_BETA","N2006_11_14_010037","N2006_11_11_220751","N2006_11_11_013125","N2006_11_11_010308","N2006_11_11_005720","N2006_11_08_233131","N2006_11_08_220332","N2006_11_07_011225","N0_20061031_BETA","start"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-33285.json"}}],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/766ISTT3KCARKFUIQT7N6WV6T63XOKG3/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSEKTKHO5HFZHWZNJNBJZA56472KRUZI/"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/08/30/1"},{"type":"ADVISORY","url":"https://github.com/tuxera/ntfs-3g/security/advisories/GHSA-q759-8j5v-q5jp"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/11/msg00013.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202301-01"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-4971"},{"type":"ADVISORY","url":"https://www.openwall.com/lists/oss-security/2021/08/30/1"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=988386"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2001608"}],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"},{"introduced":"10.0"},{"last_affected":"10.0"},{"introduced":"11.0"},{"last_affected":"11.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux"},{"cpes":["cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:34:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:35:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"33"},{"last_affected":"33"},{"introduced":"34"},{"last_affected":"34"},{"introduced":"35"},{"last_affected":"35"}],"source":"CPE_STRING","vendor_product":"fedoraproject:fedora"},{"cpes":["cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:-:*:*:*","cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:advanced_virtualization:*:*:*"],"extracted_events":[{"introduced":"7.0"},{"last_affected":"7.0"},{"introduced":"8.0"},{"last_affected":"8.0"},{"introduced":"8.0"},{"last_affected":"8.0"}],"source":"CPE_STRING","vendor_product":"redhat:enterprise_linux"}]},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
