Vulnerability identifier: #VU48894
Vulnerability risk: Low
Exploitation vector: Network
Exploit availability: No
Client/Desktop applications / Other client software
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
<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.
