The remote Amazon Linux AMI host is missing a security update.
A stack-based buffer overflow flaw was found in the way the pam_env
module parsed users' '~/.pam_environment' files. If an application's
PAM configuration contained 'user_readenv=1' (this is not the
default), a local attacker could use this flaw to crash the
application or, possibly, escalate their privileges. (CVE-2011-3148)
A denial of service flaw was found in the way the pam_env module
expanded certain environment variables. If an application's PAM
configuration contained 'user_readenv=1' (this is not the default), a
local attacker could use this flaw to cause the application to enter
an infinite loop. (CVE-2011-3149)
