Description
piao reports: Due to a bug in the Regexp compilation process, creating a Regexp object with a crafted source string could cause the same memory to be freed twice. This is known as a "double free" vulnerability. Note that, in general, it is considered unsafe to create and use a Regexp object generated from untrusted input. In this case, however, following a comprehensive assessment, we treat this issue as a vulnerability.
