Description Murray McAllister 2014-07-24 07:16:21 UTC

Multiple integer overflow issues were found in libgfortran, the run-time support library for the Fortran compiler. These could possibly be used to crash a Fortran application or cause it to execute arbitrary code.

Upstream fix:

https://gcc.gnu.org/viewcvs/gcc?limit_changes=0&view=revision&revision=211721

These will be included in a later release of GCC.
