Amazon Linux AMI : libmicrohttpd (ALAS-2014-353)

medium Nessus Plugin ID 78296

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Stack-based buffer overflow in the MHD_digest_auth_check function in libmicrohttpd before 0.9.32, when MHD_OPTION_CONNECTION_MEMORY_LIMIT is set to a large value, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long URI in an authentication header.

The MHD_http_unescape function in libmicrohttpd before 0.9.32 might allow remote attackers to obtain sensitive information or cause a denial of service (crash) via unspecified vectors that trigger an out-of-bounds read.

Solution

Run 'yum update libmicrohttpd' to update your system.
