Description Arvid Requate univentionstaff 2016-11-05 20:49:14 CET
Upstream Debian package has bee updated to version 2:3.26-1+debu7u1 which fixes:


The Network Security Service (NSS) libraries uses environment variables to configure lots of things, some of which refer to file system locations. Others can be degrade the operation of NSS in various ways, forcing compatibility modes and so on.

Previously, these environment variables were not ignored SUID binaries. This version of NetScape Portable Runtime Library (NSPR) introduce a new API, PR_GetEnVSecure, to address this.

Both NSPR and NSS need to be upgraded to address this problem.
