What an attacker can do

The source says if that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. NVD’s CVSS 3.1 assessment (base score 6.5/10) rates confidentiality and integrity impact as none; availability impact as high.
