This update for php5 fixes the following security issues :

  - CVE-2016-6294: The locale_accept_from_http function in     ext/intl/locale/locale_methods.c did not properly     restrict calls to the ICU uloc_acceptLanguageFromHTTP     function, which allowed remote attackers to cause a     denial of service (out-of-bounds read) or possibly have     unspecified other impact via a call with a long argument     (bsc#1035111).

  - CVE-2017-9227: A stack out-of-bounds read occurs in     mbc_enc_len() during regular expression searching.
    (bsc#1040883)

  - CVE-2017-9226: A heap out-of-bounds write or read occurs     in next_state_val() during regular expression     compilation. (bsc#1040889)

  - CVE-2017-9224: A stack out-of-bounds read occurs in     match_at() during regular expression searching.
    (bsc#1040891)

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)

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)
