Description
A vulnerability was found in curl. The issue occurs when curl is told to parse a .netrc file for credentials. If that file ends in a line with consecutive non-white space letters and no newline, curl could read past the end of the stack-based buffer, and if the read works, it can write a zero byte beyond its boundary. This issue, in most cases, causes a segfault or similar problem. A denial of service can occur if a malicious user can provide a custom netrc file to an application or otherwise affect its contents.
