Background
Ruby is an interpreted, high-level, general-purpose programming language known for its simplicity and productivity. The ruby1.8 package is a specific version of Ruby, which is vulnerable to a security issue. This vulnerability resides in the REXML parser, a component of the Ruby interpreter. The parser can be manipulated to allocate large string objects, potentially leading to a denial of service (crash) if an attacker exploits this behavior. This vulnerability affects the Debian 7 ecosystem.
Vulnerability Detail
The vulnerability in ruby1.8 arises from the REXML parser's susceptibility to coerced allocation of large string objects. By exploiting this flaw, remote attackers can cause the system to consume all available memory, resulting in a denial of service. This vulnerability has the potential to disrupt the normal functioning of the affected system.
