--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
The description is misleading. This bug can theoretically result in
applications receiving wrong data from NSS, and the data could even be
attacker-controlled, which means that this is a security bug.
Introduced in glibc 2.19, fixed in 2.20. The broken fix which went into glibc
2.19 has been backported to earlier glibc versions by some distributions.
