Detailsinfo

A vulnerability was found in Rubyforge RubyGems 0.8.11/0.9.0 (Programming Language Software). It has been classified as critical. This affects the function extract_files of the component Installer. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The extract_files function in installer.rb in RubyGems before 0.9.1 does not check whether files exist before overwriting them, which allows user-assisted remote attackers to overwrite arbitrary files, cause a denial of service, or execute arbitrary code via crafted GEM packages.

The bug was discovered 01/21/2007. The weakness was presented 01/23/2007 (Website). The advisory is shared at rubyforge.org. This vulnerability is uniquely identified as CVE-2007-0469 since 01/23/2007. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 27424 (openSUSE 10 Security Update : rubygems (rubygems-2644)), which helps to determine the existence of the flaw in a target environment.
