[ruby-core:84872] [Ruby trunk Bug#14359] IO#ungetbyte integer overflow
From:

Issue #14359 has been reported by shyouhei (Shyouhei Urabe).
----------------------------------------
Bug #14359: IO#ungetbyte integer overflow
https://bugs.ruby-lang.org/issues/14359
* Author: shyouhei (Shyouhei Urabe)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v:
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
In Ruby's IO, a "byte" means an integer of range 0...256.
However IO#ungetbyte is the only exception.
It does not check the argument to accept liberal integers.
```ruby
File.open("/dev/zero") {|f| f.ungetbyte(-1); p f.read(2) } # => "\xFF\x00"
File.open("/dev/zero") {|f| f.ungetbyte(257); p f.read(2) } # => "\x01\x00"
```
I see no vulnerability so just filing this as a normal bug.
