Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10 - Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Ruby.

Software Description: - ruby1.8: Object-oriented scripting language - ruby1.9.1: Object-oriented scripting language

Details:

Charlie Somerville discovered that Ruby incorrectly handled floating point number conversion. An attacker could possibly use this issue with an application that converts text to floating point numbers to cause the application to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-4164)

Vit Ondruch discovered that Ruby did not perform taint checking for certain functions. An attacker could possibly use this issue to bypass certain intended restrictions. (CVE-2013-2065)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.10:
libruby1.8 1.8.7.358-7ubuntu2.1
libruby1.9.1 1.9.3.194-8.1ubuntu2.1
ruby1.8 1.8.7.358-7ubuntu2.1
ruby1.9.1 1.9.3.194-8.1ubuntu2.1

Ubuntu 13.04:
libruby1.8 1.8.7.358-7ubuntu1.2
libruby1.9.1 1.9.3.194-8.1ubuntu1.2
ruby1.8 1.8.7.358-7ubuntu1.2
ruby1.9.1 1.9.3.194-8.1ubuntu1.2

Ubuntu 12.10:
libruby1.8 1.8.7.358-4ubuntu0.4
libruby1.9.1 1.9.3.194-1ubuntu1.6
ruby1.8 1.8.7.358-4ubuntu0.4
ruby1.9.1 1.9.3.194-1ubuntu1.6

Ubuntu 12.04 LTS:
libruby1.8 1.8.7.352-2ubuntu1.4
libruby1.9.1 1.9.3.0-1ubuntu2.8
ruby1.8 1.8.7.352-2ubuntu1.4
ruby1.9.1 1.9.3.0-1ubuntu2.8

In general, a standard system update will make all the necessary changes.

Title:	DSA-2810-1 ruby1.9.1 - heap overflow
Description:	Charlie Somerville discovered that Ruby incorrectly handled floating point number conversion. If an application using Ruby accepted untrusted input strings and converted them to floating point numbers, an attacker able to provide such input could cause the application to crash or, possibly, execute arbitrary code with the privileges of the application.
