Fixed In Version: nss_db-2.2.3-0.4.pre1.el6_2.1
Doc Type: Bug Fix
Doc Text:
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.
