This update was imported from the SUSE:SLE-15:Update update project.

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

  - An issue was discovered in RubyGems 2.6 and later     through 3.0.2. Since Gem::UserInteraction#verbose calls     say without escaping, escape sequence injection is     possible.(CVE-2019-8321)

  - 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. An attacker could potentially     use this flaw to inject SMTP commands in a SMTP session     in order to facilitate phishing attacks or spam     campaigns.(CVE-2015-9096)

  - Constructed ASN.1 types with a recursive definition     (such as can be found in PKCS7) could eventually exceed     the stack given malicious input with excessive     recursion. This could result in a Denial Of Service     attack. There are no such structures used within     SSL/TLS that come from untrusted sources so this is     considered safe. Fixed in OpenSSL 1.1.0h (Affected     1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected     1.0.2b-1.0.2n).(CVE-2016-7798)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,     Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,     prior to trunk revision 62422 contains a Directory     Traversal vulnerability in gem installation that can     result in the gem could write to arbitrary filesystem     locations during installation. This attack appear to be     exploitable via the victim must install a malicious     gem. This vulnerability appears to have been fixed in     2.7.6.(CVE-2018-1000079)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,     Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,     prior to trunk revision 62422 contains a Cross Site     Scripting (XSS) vulnerability in gem server display of     homepage attribute that can result in XSS. This attack     appear to be exploitable via the victim must browse to     a malicious gem on a vulnerable gem server. This     vulnerability appears to have been fixed in     2.7.6.(CVE-2018-1000078)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,     Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,     prior to trunk revision 62422 contains a Improper Input     Validation vulnerability in ruby gems specification     homepage attribute that can result in a malicious gem     could set an invalid homepage URL. This vulnerability     appears to have been fixed in 2.7.6.(CVE-2018-1000077)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,     Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,     prior to trunk revision 62422 contains a     Deserialization of Untrusted Data vulnerability in     owner command that can result in code execution. This     attack appear to be exploitable via victim must run the     `gem owner` command on a gem with a specially crafted     YAML file. This vulnerability appears to have been     fixed in 2.7.6.(CVE-2018-1000074)

  - RubyGems version Ruby 2.2 series: 2.2.9 and earlier,     Ruby 2.3 series: 2.3.6 and earlier, Ruby 2.4 series:
    2.4.3 and earlier, Ruby 2.5 series: 2.5.0 and earlier,     prior to trunk revision 62422 contains a Directory     Traversal vulnerability in install_location function of     package.rb that can result in path traversal when     writing to a symlinked basedir outside of the root.
    This vulnerability appears to have been fixed in     2.7.6.(CVE-2018-1000073)

  - Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before     2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an     HTTP Response Splitting attack. An attacker can inject     a crafted key and value into an HTTP response for the     HTTP server of WEBrick.(CVE-2017-17742)

  - Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x     through 2.6.4 allows HTTP Response Splitting. If a     program using WEBrick inserts untrusted input into the     response header, an attacker can exploit it to insert a     newline character to split a header, and inject     malicious content to deceive clients. NOTE: this issue     exists because of an incomplete fix for CVE-2017-17742,     which addressed the CRLF vector, but did not address an     isolated CR or an isolated LF.(CVE-2019-16254)
