Description Florian Weimer 2015-10-30 19:10:28 UTC

Apply the following upstream patches:

https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=a014cecd82b71b70a6a843e250e06b541ad524f7
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=f586e1328681b400078c995a0bb6ad301ef73549

These will provide additional hardening to make exploitation of memory safety violations more difficult.
