CVE-2018-1000120

Existe un desbordamiento de búfer en curl, de la versión 7.12.3 a la 7.58.0, en la gestión de URL FTP que permite que un atacante provoque una denegación de servicio (DoS) o algo peor.

It was found that libcurl did not safely parse FTP URLs when using the CURLOPT_FTP_FILEMETHOD method. An attacker, able to provide a specially crafted FTP URL to an application using libcurl, could write a NULL byte at an arbitrary location, resulting in a crash or an unspecified behavior.

Phan Thanh discovered that curl incorrectly handled certain FTP paths. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Dario Weisser discovered that curl incorrectly handled certain LDAP URLs. An attacker could possibly use this issue to cause a denial of service. Max Dymond discovered that curl incorrectly handled certain RTSP data. An attacker could possibly use this to cause a denial of service or even to get access to sensitive data. Various other issues were also addressed.
