CVE-2017-0898: Buffer underrun vulnerability in Kernel.sprintf
If a malicious format string which contains a precious specifier (*) is passed and a huge minus value is also passed to the specifier, buffer underrun may be caused. In such situation, the result may contains heap, or the Ruby interpreter may crash.
CVE-2017-10784: Escape sequence injection vulnerability in the Basic authentication of WEBrick
When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject malicious escape sequences to the log and dangerous control characters may be executed on a victim's terminal emulator.
This vulnerability is similar to a vulnerability already fixed, but it had not been fixed in the Basic authentication.
