Summary
curl can be told to parse a `.netrc` file for credentials. 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.
