ruby1.9.1 - security update

Multiple vulnerabilities were discovered in the interpreter for the Ruby
language:

• CVE-2014-4975
  The encodes() function in pack.c had an off-by-one error that could
  lead to a stack-based buffer overflow. This could allow remote
  attackers to cause a denial of service (crash) or arbitrary code
  execution.
• CVE-2014-8080,
  CVE-2014-8090
  The REXML parser could be coerced into allocating large string
  objects that could consume all available memory on the system. This
  could allow remote attackers to cause a denial of service (crash).

For the stable distribution (wheezy), these problems have been fixed in
version 1.9.3.194-8.1+deb7u3.

For the upcoming stable distribution (jessie), these problems have been
fixed in version 2.1.5-1 of the ruby2.1 source package.

For the unstable distribution (sid), these problems have been fixed in
version 2.1.5-1 of the ruby2.1 source package.

We recommend that you upgrade your ruby1.9.1 packages.
