CVSS: 6.8EPSS: 2%CPEs: 38EXPL: 0CVE-2011-0188 – ruby: memory corruption in BigDecimal on 64bit platforms
https://notcve.org/view.php?id=CVE-2011-0188
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue." La función VpMemAlloc en bigdecimal.c en la clase BigDecimal en Ruby v1.9.2-P136 y anteriores, tal como se utiliza en Apple Mac OS X antes de vv10.6.7 y en otras plataformas, no asigna memoria adecuadamente, lo que permite a atacantes dependientes de contexto ejecutar código de su elección o causar una denegación de servicio (caída de aplicación) a través de vectores que impliquen la creación de un valor BigDecimal grande dentro de un proceso de 64 bits, relacionado con un "fallo de truncado de entero". • http://lists.apple.com/archives/security-announce/2011/Mar/msg00006.html http://support.apple.com/kb/HT4581 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/ext/bigdecimal/bigdecimal.c?r1=29364&r2=30993 http://www.mandriva.com/security/advisories?name=MDVSA-2011:097 http://www.mandriva.com/security/advisories?name=MDVSA-2011:098 http://www.redhat.com/support/errata/RHSA-2011-0908.html http://www.redhat.com/support/errata/RHSA-2011-0909.html http://www.redhat.com/support/ • CWE-189: Numeric Errors •
