The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has curl packages installed that are affected by multiple vulnerabilities:
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content… This vulnerability appears to have been fixed in curl < 7.20.0 and curl >= 7.60.0. (CVE-2018-1000301)
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. (CVE-2018-1000120)
A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply.
(CVE-2018-1000121)
A buffer over-read exists in curl 7.20.0 to and including curl 7.58.0 in the RTSP+RTP handling code that allows an attacker to cause a denial of service or information leakage (CVE-2018-1000122)
It was found that curl and libcurl might send their Authentication header to a third party HTTP server upon receiving an HTTP REDIRECT reply. This could leak authentication token to external entities.
(CVE-2018-1000007)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
