Package : ruby2.3
CVE ID : CVE-2017-0898 CVE-2017-0903 CVE-2017-10784 CVE-2017-14033
Debian Bug : 875928 875931 875936 879231

Several vulnerabilities have been discovered in the interpreter for the
Ruby language. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2017-0898

aerodudrizzt reported a buffer underrun vulnerability in the sprintf
method of the Kernel module resulting in heap memory corruption or
information disclosure from the heap.

CVE-2017-0903

Max Justicz reported that RubyGems is prone to an unsafe object
deserialization vulnerability. When parsed by an application which
processes gems, a specially crafted YAML formatted gem specification
can lead to remote code execution.

CVE-2017-10784

Yusuke Endoh discovered an escape sequence injection vulnerability
in the Basic authentication of WEBrick. An attacker can take
advantage of this flaw to inject malicious escape sequences to the
WEBrick log and potentially execute control characters on the
victim's terminal emulator when reading logs.

CVE-2017-14033

asac reported a buffer underrun vulnerability in the OpenSSL
extension. A remote attacker can take advantage of this flaw to
cause the Ruby interpreter to crash leading to a denial of service.

For the stable distribution (stretch), these problems have been fixed in
version 2.3.3-1+deb9u2.

We recommend that you upgrade your ruby2.3 packages.
