According to the versions of the ruby packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - 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.(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 stack out-of-bounds read occurs in     mbc_enc_len() during regular expression searching.
    Invalid handling of reg->dmin in forward_search_range()     could result in an invalid pointer dereference, as an     out-of-bounds read from a stack buffer.(CVE-2017-9227)

  - 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 heap out-of-bounds write occurs in     bitset_set_range() during regular expression     compilation due to an uninitialized variable from an     incorrect state transition. An incorrect state     transition in parse_char_class() could create an     execution path that leaves a critical local variable     uninitialized until it's used as an index, resulting in     an out-of-bounds write memory     corruption.(CVE-2017-9228)

  - 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 read occurs in     match_at() during regular expression searching. A     logical error involving order of validation and access     in match_at() could result in an out-of-bounds read     from a stack buffer.(CVE-2017-9224)

  - A SMTP command injection flaw was found in the way     Ruby's Net::SMTP module handled CRLF sequences in     certain SMTP commands.
