CVE-2013-4164 – ruby: heap overflow in floating point parsing

https://notcve.org/view.php?id=CVE-2013-4164

Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using (1) the to_f method or (2) JSON.parse. Desbordamiento de buffer basado en memoria dinámica en Ruby 1.8, 1.9 anteriores a 1.9.3-p484, 2.0 anteriores a 2.0.0-p353, 2.1 anteriores a 2.1.0 preview2, y "trunk" anteriores a la revisión 43780 permite a atacatnes dependientes del contexto causar denegación de servicio (segmentation fault) y posiblemente ejecutar código arbitrario a través de una cadena de texto que es convertida a un número en punto flotante, como demostrado utilizando (1) el método to_f o (2) JSON.parse. • http://archives.neohapsis.com/archives/bugtraq/2014-04/0134.html http://archives.neohapsis.com/archives/bugtraq/2014-10/0103.html http://lists.opensuse.org/opensuse-security-announce/2013-12/msg00009.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00027.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00028.html http://osvdb.org/100113 http://rhn.redhat.com/errata/RHSA-2013-1763.html http://rhn.redhat.com/errata/RHSA-2013-1764.html http://rhn.redhat.com/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
