The manipulation with an unknown input leads to a numeric error vulnerability. CWE is classifying the issue as CWE-189. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Multiple integer overflows in the rb_ary_store function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, and 1.8.7 before 1.8.7-p22 allow context-dependent attackers to execute arbitrary code or cause a denial of service via unknown vectors, a different issue than CVE-2008-2662, CVE-2008-2664, and CVE-2008-2725. NOTE: as of 20080624, there has been inconsistent usage of multiple CVE identifiers related to Ruby. The CVE description should be regarded as authoritative, although it is likely to change.

The bug was discovered 06/20/2008. The weakness was disclosed 06/24/2008 with Apple Product Security (Website). The advisory is available at ruby-lang.org. This vulnerability is traded as CVE-2008-2663 since 06/10/2008. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 43694 (CentOS 4 / 5 : ruby (CESA-2008:0561)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117264 (CentOS Security Update for Ruby (CESA-2008:0562)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (43346) and Tenable (43694). The entries 3775, 3754, 3750 and 3753 are pretty similar.
