NanaZip is an open source file archive Starting in version 5.0.1252.0 and prior to version 6.0.1630.0, NanaZip has an out-of-bounds heap read in .NET Single File bundle header parser due to missing bounds check. Opening a crafted file with NanaZip causes a crash or leaks heap data to the user. Version 6.0.1630.0 patches the issue.
Weakness
The product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer.
