Only the syntax and order of the ranges are checked, so row=1-400000000 on a two-line file allocates 400 million elements.\n\nAn application that passes a request-supplied fragment to fragment or csv can be made to exhaust memory, which ends the process with an Out of memory error that eval cannot catch.\n\n## Affected\n\n- `Text-CSV_XS < 1.65`\n\n## Remediation\n\nUpgrade to Text-CSV_XS 1.65 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
