CVE Request -- glibc: Integer overflows, leading to stack-based buffer overflows in strto* related routines
From: Jan Lieskovsky <jlieskov () redhat com>

Hello Kurt, Steve, vendors,

  multiple integer overflows, leading to stack-based buffer overflows were found in various stdlib functions of GNU 
libc (strtod, strtof, strtold, strtod_l and related routines). If an application, using the affected stdlib functions, 
did not perform user-level sanitization of provided inputs, a local attacker could use this flaw to cause such an 
application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Upstream bug report:
[1] http://sourceware.org/bugzilla/show_bug.cgi?id=14459

Upstream patch (might not be the final one):
[2] http://sourceware.org/ml/libc-alpha/2012-08/msg00202.html

References:
[3] https://bugzilla.redhat.com/show_bug.cgi?id=847715

Could you allocate a CVE id for this?

Thank you && Regards, Jan.
