Attackers can code a CTU in a second slice so a bi-predicted BDOF coding unit carries a negative reference index, causing Slice::getRefPic to read outside m_apcRefPicList and crash decoding.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","cwes":["CWE-129"],"vendors":[],"products":[],"references":[{"url":"https://github.com/fraunhoferhhi/vvdec","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.0/source/Lib/CommonLib/InterPrediction.cpp#L609-L631","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.0/source/Lib/CommonLib/Slice.h#L2645","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/32b842c10bf024f09bc7cf1445fa6f8a987422ca","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/6e4b907ef5ab9db390b1293ba1ad5d7dd0a67e3f","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/402","tags":[]},{"url":"https://www.vulncheck.com/advisories/fraunhofer-hhi-vvdec-before-3.2.1-out-of-bounds-read-via-slice-getrefpic","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/402","tags":[]}],"exploitRefs":[{"url":"https://github.com/fraunhoferhhi/vvdec","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.0/source/Lib/CommonLib/InterPrediction.cpp#L609-L631","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/blob/v3.2.0/source/Lib/CommonLib/Slice.h#L2645","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/32b842c10bf024f09bc7cf1445fa6f8a987422ca","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/commit/6e4b907ef5ab9db390b1293ba1ad5d7dd0a67e3f","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/402","tags":[]},{"url":"https://github.com/fraunhoferhhi/vvdec/issues/402","tags":[]}],"hasPoc":true,"ai":null}
