- Summary
- .netrc parser out-of-bounds access
- Details
-
curl can be told to parse a
.netrcfile 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, write a zero byte possibly beyond its boundary.This does 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.
