The nd_decode function may read up to 15 bytes without checking the actual length of the supplied Python buffer. The nd_decode_ex, nd_decode_ex2, and nd_decode_with_context functions pass the caller-supplied buffer size to the decoder without validating it against the actual length of the Python buffer. Data read beyond the buffer may be exposed through nd_get_instrux_bytes, which returns a fixed-length list of 16 bytes. Exploitation requires an application to invoke the affected APIs with a short buffer or an oversized length and to expose the resulting bytes to an attacker. The pybddisasm package is no longer maintained.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":4.8,"severity":"medium","source":"CNA: Bitdefender","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.8,"severity":"medium","source":"NVD: cve-requests@bitdefender.com","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"}],"modifiedAt":1793697430937,"publishedAt":1793696436256,"references":[{"source":"CNA: Bitdefender","tags":[],"url":"https://pypi.org/project/pybddisasm/"},{"source":"cve-requests@bitdefender.com","tags":[],"url":"https://pypi.org/project/pybddisasm/"}],"remediation":[{"kind":"fix","source":"CNA: Bitdefender","text":"Discontinue use of the unmaintained pybddisasm package.
