Net::SMTP in Ruby before 2.4.0 is vulnerable to SMTP command injection via CRLF sequences in a RCPT TO or MAIL FROM command, as demonstrated by CRLF sequences immediately before and after a DATA substring. El modulo Net::SMTP de Ruby anterior a su versión 2.4.0 es vulnerable a la inyección de comandos SMTP mediante secuencias CRLF de los comandos "RCPT TO" o "MAIL FROM", como demuestra las secuencias CRLF inmediatamente antes y después de la substring DATA. • http://www.mbsd.jp/Whitepaper/smtpi.pdf https://github.com/ruby/ruby/commit/0827a7e52ba3d957a634b063bf5a391239b9ffee https://github.com/rubysec/ruby-advisory-db/issues/215 https://hackerone.com/reports/137631 https://lists.debian.org/debian-lts-announce/2018/07/msg00012.html https://www.debian.org/security/2017/dsa-3966 • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2017-9229 – oniguruma: Invalid pointer dereference in left_adjust_char_head()
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 •

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 •

The parse_char_class function in regparse.c in the Onigmo (aka Oniguruma-mod) regular expression library, as used in Ruby 2.4.0, allows remote attackers to cause a denial of service (deep recursion and application crash) via a crafted regular expression. La función parse_char_class en regparse.c en la Onigmo (también conocida como Oniguruma-mod) libreria de expresión regular,como se utiliza en Ruby 2.4.0, permite a atacantes remotos provocar una denegación de servicio (recursión profunda y caída de la aplicación) a través de una expresión regular manipulada. • http://www.securityfocus.com/bid/97304 https://bugs.ruby-lang.org/issues/13234 https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/57660 • CWE-20: Improper Input Validation •
