Descriptions

curl and libcurl 7.2x before 7.24.0 do not properly consider special characters during extraction of a pathname from a URL, which allows remote attackers to conduct data-injection attacks via a crafted URL, as demonstrated by a CRLF injection attack on the (1) IMAP, (2) POP3, or (3) SMTP protocol.

curl y libcurl v7.2x anteriores v7.24.0 no consideran de forma adecuada los caracteres especiales cuando extraen una ruta de un fichero de una URL, lo que permite a atacantes remotos realizar ataques de injección de datos mediente una URL manipulada, como se demostró mediante un atque de injección CRLF sobre los protocolos (1) IMAP, (2) POP3, y (3) SMTP.
