Attackers can craft a VVC bitstream enabling TMVP with a smaller collocated reference picture, causing getColInfo to read past the colMotion allocation when error concealment is enabled.","cvssScore":4.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/fraunhoferhhi/vvdec","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/CodingStructure.cpp#L453-L458","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/Slice.cpp#L1819-L1859","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/0695c06221c27b3680fec9851ac2cf46b2195ea9","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/422","tags":[]},{"url":"https://www.vulncheck.com/advisories/fraunhofer-hhi-vvdec-through-3.2.1-heap-out-of-bounds-read-via-codingstructure-getcolinfo","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/422","tags":[]}],"exploitRefs":[{"url":"https://github.com/fraunhoferhhi/vvdec","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/CodingStructure.cpp#L453-L458","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.1/source/Lib/CommonLib/Slice.cpp#L1819-L1859","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/0695c06221c27b3680fec9851ac2cf46b2195ea9","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/422","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/422","tags":[]}],"hasPoc":true,"ai":null}
