- Summary
- URL globbing out of bounds read
- Details
-
curl supports "globbing" of URLs, in which a user can pass a numerical range to have the tool iterate over those numbers to do a sequence of transfers.
In the globbing function that parses the numerical range, there was an omission that made curl read a byte beyond the end of the URL if given a carefully crafted, or just wrongly written, URL. The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing.
An example of a URL that triggers the flaw would be
http://ur%20[0-60000000000000000000. - Database specific
