Attackers can supply a crafted MPEG file opened via SMPEG_new, SMPEG_new_rwops or SMPEG_new_data to trigger a reachable assertion or out-of-bounds copy, crashing the application.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-191"],"vendors":[],"products":[],"references":[{"url":"https://github.com/icculus/smpeg","tags":[]},{"url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L295-L350","tags":[]},{"url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L777","tags":[]},{"url":"https://hackmd.io/@haindpwn/smpeg-system-header-stream-table-oob-read","tags":[]},{"url":"https://www.vulncheck.com/advisories/smpeg-through-2.0.0-integer-underflow-via-stream-header-in-mpegsystem-cpp","tags":[]}],"exploitRefs":[{"url":"https://github.com/icculus/smpeg","tags":[]},{"url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L295-L350","tags":[]},{"url":"https://github.com/icculus/smpeg/blob/d188dc111f4817288718705e4a84e248803ccfdc/MPEGsystem.cpp#L777","tags":[]}],"hasPoc":true,"ai":null}
