Attackers can supply a malicious BitLocker volume image with a datum_size smaller than the 36-byte AES-CCM header, causing hexdump() to over-read and crash dislocker.","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/Aorimn/dislocker","tags":[]},{"url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/fvek.c#L90-L105","tags":[]},{"url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/vmk.c#L146-L180","tags":[]},{"url":"https://github.com/Aorimn/dislocker/commit/0706462db88efe8df88150e4c3e4332b808f4581","tags":[]},{"url":"https://www.vulncheck.com/advisories/dislocker-through-0.7.3-out-of-bounds-heap-read-via-vmk-fvek-datum-size-underflow","tags":[]}],"exploitRefs":[{"url":"https://github.com/Aorimn/dislocker","tags":[]},{"url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/fvek.c#L90-L105","tags":[]},{"url":"https://github.com/Aorimn/dislocker/blob/v0.7.3/src/metadata/vmk.c#L146-L180","tags":[]},{"url":"https://github.com/Aorimn/dislocker/commit/0706462db88efe8df88150e4c3e4332b808f4581","tags":[]}],"hasPoc":true,"ai":null}
