REDHAT-BUG-1165192
First published: Tue Nov 18 2014(Updated: )
IssueDescription: The "files" backend for the Name Service Switch (NSS) in glibc does not properly isolate iteration over the entire database from key-based lookups. As a result, an application which performs lookups on a database while iterating over it could enter an infinite loop, leading to a denial of service. Acknowledgements: This issue was discovered by Robin Hack of Red Hat.
