Published: December 9, 2020 / Updated: October 28, 2023
cURL
curl.haxx.se
Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due tu uncontrolled recursion when processing FTP responses within the wildcard matching functionality, which allows a callback (set
with <a href="https://curl.se/libcurl/c/CURLOPT_CHUNK_BGN_FUNCTION.html">CURLOPT_CHUNK_BGN_FUNCTION</a>) to return information back to libcurl on
how to handle a specific entry in a directory when libcurl iterates over a
list of all available entries. A remote attacker who controls the malicious FTP server can trick the victim to connect to it and crash the application, which is using the affected libcurl version.
