CVE-2020-8285 – curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used
https://notcve.org/view.php?id=CVE-2020-8285
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. curl versiones 7.21.0 hasta 7.73.0 e incluyéndola, es vulnerable a una recursividad no controlada debido a un problema de desbordamiento de la pila en el análisis de coincidencias del comodín FTP Libcurl offers a wildcard matching functionality, which allows a callback (set with `CURLOPT_CHUNK_BGN_FUNCTION`) 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. When this callback returns `CURL_CHUNK_BGN_FUNC_SKIP`, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. • http://seclists.org/fulldisclosure/2021/Apr/51 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8285.html https://github.com/curl/curl/issues/6255 https://hackerone.com/reports/1045844 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts • CWE-121: Stack-based Buffer Overflow CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •
