Upgrade Debian:12 curl to version 7.55.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian.
See How to fix? for Debian:12 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.
