Red Hat Security Advisory 2014-1744-01 – V8 is Google’s open source JavaScript engine. It was discovered that V8 did not properly check the stack size limit in certain cases. A remote attacker able to send a request that caused a script executed by V8 to use deep recursion could trigger a stack overflow, leading to a crash of an application using V8. Multiple flaws were discovered in V8. Untrusted JavaScript code executed by V8 could use either of these flaws to crash V8 or, possibly, execute arbitrary code with the privileges of the user running V8.
