Description Victor Pereira 2015-09-11 08:13:37 UTC 
rh#1260711

The XSLTProcessor class misses a few checks on the input from the libxslt library. The valuePop() function call is able to return NULL pointer and php does not check that.

yes it looks like its the same issue. But if they didn't fix it then the patch is incomplete.
