How does it work...
To mitigate this class of attacks we will be doing the following :
- Linux Kernels are being released immediately.
- glibc packages are being released immediately.
- gcc (GNU Compiler Collection) updates will be released in the near future.
- Various applications might be updated in the near future.

For customers with active LTSS Subscriptions for SLES 10 SP4 it is required to open a Service Request through the SUSE Customer Center and request a PTF.
Older SUSE Linux Enterprise versions already had variable heap-stack-gap support.
As such, on SUSE Linux Enterprise 10, it is possible to use a sysctl variable to adjust the heap stack gap.
Temporary during run-time :
echo 256 > /proc/sys/vm/heap-stack-gapPermanently by adding the following line into /etc/sysctl.conf
vm.heap-stack-gap = 256
