Amazon Linux AMI : curl (ALAS-2015-514)
high Nessus Plugin ID 83057
Language:
Synopsis
The remote Amazon Linux AMI host is missing a security update.Description
It was discovered that libcurl could incorrectly reuse NTLM-authenticated connections for subsequent unauthenticated requests to the same host. If an application using libcurl established an NTLM-authenticated connection to a server, and sent subsequent unauthenticed requests to the same server, the unauthenticated requests could be sent over the NTLM-authenticated connection, appearing as if they were sent by the NTLM authenticated user.(CVE-2015-3143)
It was discovered that libcurl could incorrectly reuse Negotiate authenticated HTTP connections for subsequent requests. If an application using libcurl established a Negotiate authenticated HTTP connection to a server and sent subsequent requests with different credentials, the connection could be re-used with the initial set of credentials instead of using the new ones. (CVE-2015-3148)
It was discovered that libcurl did not properly process cookies with a specially crafted 'path' element. If an application using libcurl connected to a malicious HTTP server sending specially crafted 'Set-Cookies' headers, this could lead to an out-of-bounds read, and possibly cause that application to crash. (CVE-2015-3145)
It was discovered that libcurl did not properly process zero-length host names. If an attacker could trick an application using libcurl into processing zero-length host names, this could lead to an out-of-bounds read, and possibly cause that application to crash.
(CVE-2015-3144)
