This Affects:
axum-extraTL;DR
Affected versions of this package are vulnerable to an integer underflow in the FileStream::try_range_response function when handling empty files, which may lead to denial of service (DoS); this vulnerability occurs due to improper calculation of range responses for zero-size files, causing an integer underflow that can result in memory corruption or application crash. An attacker can exploit this by sending a malicious range request targeting an empty file, triggering the underflow, and potentially crashing the service, thereby causing a DoS condition.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
