Date: Sat, 22 Aug 2009 14:22:07 +0200 From: Florian Weimer <fw@...eb.enyo.de> To: oss-security@...ts.openwall.com Subject: Using NSS (Netscape Security Services) in setuid programs NSS (the crypto library from Mozilla) uses environment variables to enable various dodgy features which no longer seem good ideas. Obviously, this is a problem when the library is used in a context where the attacker can set environment variables. For instance, if a PAM module uses NSS to establish a TLS connection for authentication purposes, this allows a local attacker to enable features which make it easier to impersonate the authentication server. I couldn't find any programs which might suffer from such a problem, though.
