Amazon Linux AMI : curl (ALAS-2018-995)
High Nessus Plugin ID 109184
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionFTP path trickery leads to NIL byte out of bounds write :
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)
LDAP NULL pointer dereference :
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)
RTSP RTP buffer over-read :
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)
SolutionRun 'yum update curl' to update your system.
