CVE-2007-0469

https://notcve.org/view.php?id=CVE-2007-0469

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. La función extract_files en installer.rb de RubyGems before 0.9.1 no comprueba la existencia ficheros antes de sobrescribirlos, lo cual permite a atacantes remotos con la complicidad del usuario sobrescribir ficheros de su elección, provocar una denegación de servicio, o ejecutar código de su elección mediante paquetes GEM artesanales. • http://marc.info/?l=full-disclosure&m=116939816621060&w=2 http://rubyforge.org/frs/shownotes.php?release_id=9074 http://www.novell.com/linux/security/advisories/2007_4_sr.html http://www.securityfocus.com/archive/1/458128/100/0/threaded http://www.vupen.com/english/advisories/2007/0295 https://exchange.xforce.ibmcloud.com/vulnerabilities/31688 •
