Descriptions
Curl_smtp_escape_eob in lib/smtp.c in curl 7.54.1 to and including curl 7.60.0 has a heap-based buffer overflow that might be exploitable by an attacker who can control the data that curl transmits over SMTP with certain settings (i.e., use of a nonstandard --limit-rate argument or CURLOPT_BUFFERSIZE value).
Curl_smtp_escape_eob en lib/smtp.c en curl desde la versión 7.54.1 hasta la 7.60.0 tiene un desbordamiento de búfer basado en memoria dinámica (heap) que podría ser explotado por un atacante que pueda controlar los datos que curl transmite por SMTP con ciertas opciones (p.ej., el uso de un argumento no estándar --limit-rate o un valor CURLOPT_BUFFERSIZE).
A heap-based buffer overflow has been found in the Curl_smtp_escape_eob() function of curl. An attacker could exploit this by convincing a user to use curl to upload data over SMTP with a reduced buffer to cause a crash or corrupt memory.
