Issue Date:        2013-02-21
CVE Numbers:       CVE-2011-3148
                    CVE-2011-3149
--

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)
