CVSS 3.1
8.1 highCVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:HCVE-2024-53427
High (8.1) in jqlang jq. EPSS 0.4% chance of exploitation in the next 30 days.
decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string with NaN (e.g., "1 NaN123" immediately followed by many more digits).
