Debian DSA-2810-1 : ruby1.9.1 - heap overflow

medium Nessus Plugin ID 71221

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the ruby1.9.1 packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.9.2.0-2+deb6u2.

For the stable distribution (wheezy), this problem has been fixed in version 1.9.3.194-8.1+deb7u2.
