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).
--------------------------------------------------------------------------------

* Wed Apr 7 2010 Nalin Dahyabhai <nalin at redhat.com> - 2.2-46
