>Description:
lang/php5 5.3.4 is vulnerable to a DoS attack involving floating point numbers (when compiled with the default CFLAGS).
>How-To-Repeat:
Compile php5 from ports without specifying SSE math instructions. The produced 387 instructions will cause PHP to infinite loop on certain floating point numbers.
>Fix:
Arch Linux has a "PHP 5.3.5" but AFAICT it's not been released yet. One workaround is to enable SSE instructions at compile-time.
