CVSS: 5.0EPSS: 18%CPEs: 51EXPL: 1CVE-2008-3443 – Ruby 1.9 - regex engine Remote Socket Memory Leak
https://notcve.org/view.php?id=CVE-2008-3443
The regular expression engine (regex.c) in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 allows remote attackers to cause a denial of service (infinite loop and crash) via multiple long requests to a Ruby socket, related to memory allocation failure, and as demonstrated against Webrick. El motor de expresiones regulares (regex.c) en Ruby 1.8.5 y anteriores, 1.8.6 a través de p286-1.8.6, 1.8.7 a través de 1.8.7-p71, y 1.9 a través de r18423 permite a atacantes remotos provocar una denegación de servicio (bucle infinito y caida) a través de múltiples peticiones largas a un socket de Ruby. Esta denegación de servicio esta relacionada con un fallo en la asignación de memoria, como se ha demostrado contra Webrick. • https://www.exploit-db.com/exploits/6239 http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://secunia.com/advisories/31430 http://secunia.com/advisories/32165 http://secunia.com/advisories/32219 http://secunia.com/advisories/32371 http://secunia.com/advisories/32372 http://secunia.com/advisories/33185 http://secunia.com/advisories/33398 http://secunia.com/advisories/35074 http://securityreason.com/securityalert/4158 http://support.apple.com/kb/HT3549 • CWE-399: Resource Management Errors •

The dl module in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen.

Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not properly restrict access to critical variables and methods at various safe levels, which allows context-dependent attackers to bypass intended access restrictions via (1) untrace_var, (2) $PROGRAM_NAME, and (3) syslog at safe level 4, and (4) insecure methods at safe levels 1 through 3. Ruby versiones 1.8.5 y anteriores, versiones 1.8.6 hasta 1.8.6-p286, versiones 1.8.7 hasta 1.8.7-p71, y versiones 1.9 hasta r18423, no restringe apropiadamente el acceso a variables y métodos críticos en varios niveles seguros, lo que permite a los atacantes dependiendo del contexto omitir las restricciones de acceso previstas por medio de (1) untrace_var, (2) $PROGRAM_NAME, y (3) syslog en nivel seguro 4 y (4) métodos no confiables en los niveles seguros 1 a 3. • https://www.exploit-db.com/exploits/32224 https://www.exploit-db.com/exploits/32223 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=494401 http://lists.apple.com/archives/security-announce/2009/May/msg00002.html http://secunia.com/advisories/31430 http://secunia.com/advisories/31697 http://secunia.com/advisories/32165 http://secunia.com/advisories/32219 http://secunia.com/advisories/32255 http://secunia.com/advisories/32256 http://secunia.com/advisories/32371 http:// • CWE-264: Permissions, Privileges, and Access Controls •
