4.201. nss_db
An updated nss_db package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The nss_db package contains a set of C library extensions, such as the Name Service Switch (nsswitch) module, which allow Berkeley Databases to be used as a primary source of aliases, groups, hosts, networks, protocols, users, services, or shadow passwords instead of, or in addition to, using flat files or the Network Information Service (NIS).
Bug Fix
- BZ#788668
- The previous update of nss_db attempted to fix a bug, which under certain circumstances prevented multi-threaded applications from obtaining complete lists of user's supplemental group memberships. This problem was not completely fixed due to an internal error that occurred when using an insufficiently large temporary buffer to parse a group entry with a large list of users. This update resolves the issue by resetting the buffer's contents after the buffer has been resized. Large group lists are thus correctly parsed and the entire list of user's supplemental groups is now correctly listed in this scenario.
All users of nss_db are advised to upgrade to this updated package, which fixes this bug.
