The Mozilla Foundation Security Advisory describes this flaw as: When calling JS::CheckRegExpSyntax
a Syntax Error could have been set which would end in calling convertToRuntimeErrorAndClear
. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error.
