An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds write in onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow. Se descubrió un problema en Oniguruma versión 6.2.0, tal como es usado en Oniguruma-mod en Ruby hasta la versión 2.4.1 y mbstring en PHP hasta la versión 7.1.5. • https://github.com/kkos/oniguruma/commit/166a6c3999bf06b4de0ab4ce6b088a468cc4029f https://github.com/kkos/oniguruma/issues/56 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-9229
An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition. Se descubrió un problema en Oniguruma versión 6.2.0, como es usado en Oniguruma-mod en Ruby hasta versión 2.4.1 y mbstring en PHP hasta versión 7.1.5. Un SIGSEGV se produce en la función left_adjust_char_head() durante la compilación de expresiones regulares. • https://access.redhat.com/errata/RHSA-2018:1296 https://github.com/kkos/oniguruma/commit/b690371bbf97794b4a1d3f295d4fb9a8b05d402d https://github.com/kkos/oniguruma/issues/59 https://access.redhat.com/security/cve/CVE-2017-9229 https://bugzilla.redhat.com/show_bug.cgi?id=1466746 • CWE-476: NULL Pointer Dereference CWE-787: Out-of-bounds Write •

Type confusion exists in two methods of Ruby's WIN32OLE class, ole_invoke and ole_query_interface. Attacker passing different type of object than this assumed by developers can cause arbitrary code execution. Existe un tipo de confusión en dos métodos de la clase WIN32OLE de Ruby, ole_invoke y ole_query_interface. El atacante que pasa un diferente tipo de objeto del que es asumido por los desarrolladores puede provocar la ejecución de código arbitrario. • http://www.talosintelligence.com/reports/TALOS-2016-0029 •

An exploitable heap overflow vulnerability exists in the Fiddle::Function.new "initialize" function functionality of Ruby. In Fiddle::Function.new "initialize" heap buffer "arg_types" allocation is made based on args array length. Specially constructed object passed as element of args array can increase this array size after mentioned allocation and cause heap overflow. Existe una vulnerabilidad explotable de desbordamiento de memoria dinámica en la funcionalidad Fiddle::Function.new "initialize" de Ruby. En Fiddle::Function.new "initialize" la ubicación "arg_types" de la memoria dinámica del búfer se hace en base a la longitud de los args array. • http://www.securityfocus.com/bid/91234 http://www.talosintelligence.com/reports/TALOS-2016-0034 https://lists.debian.org/debian-lts-announce/2018/07/msg00012.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
