Description Doran Moppert 2018-10-23 22:07:30 UTC
A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. 

*Note: 64-bit builds are not vulnerable to this issue.*
