Name        : nss_db
Product     : Fedora 11
Version     : 2.2
Release     : 46.fc11
URL         : http://sources.redhat.com/glibc/
Summary     : An NSS library for the Berkeley DB
Description :
Nss_db is a set of C library extensions which allow Berkeley Databases
to be used as a primary source of aliases, ethers, groups, hosts,
networks, protocol, users, RPCs, services, and shadow passwords
(instead of or in addition to using flat files or NIS). Install nss_db
if your flat name service files are too large and lookups are slow.

--------------------------------------------------------------------------------
Update Information:

Stephane Chazelas reported that the nss_db module attempts to read a DB_CONFIG
file in the current directory when it is used.  If the contents of the file
can't be parsed properly, the copy of libdb which nss_db uses will print an
error message.  If nss_db is invoked from a setuid process, it may then expose
privileged information to the unprivileged user who started the process.  This
update imports Kees Cook's fix for the issue (CVE-2010-0826).
--------------------------------------------------------------------------------
