NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-dotnet20-curl package and not the rh-dotnet20-curl package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
