CVE-2022-35260 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 1.76% chance of exploitation in the next 30 days.
