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

  - A use-after-free in onig_new_deluxe() in regext.c in     Oniguruma 6.9.2 allows attackers to potentially cause     information disclosure, denial of service, or possibly     code execution by providing a crafted regular     expression. The attacker provides a pair of a regex     pattern and a string, with a multi-byte encoding that     gets handled by onig_new_deluxe(). Oniguruma issues     often affect Ruby, as well as common optional libraries     for PHP and Rust.(CVE-2019-13224)

  - PHP 7.1.5 has an Out of bounds access in     php_pcre_replace_impl via a crafted preg_replace     call.(CVE-2017-9118)

  - Double free vulnerability in the php_wddx_process_data     function in wddx.c in the WDDX extension in PHP before     5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8     allows remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via crafted XML data that is mishandled in a     wddx_deserialize call.(CVE-2016-5772)

  - When using fgetss() function to read data with     stripping tags, in PHP versions 7.2.x below 7.2.27,     7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible     to supply data that will cause this function to read     past the allocated buffer. This may lead to information     disclosure or crash.(CVE-2020-7059)

  - When using certain mbstring functions to convert     multibyte encodings, in PHP versions 7.2.x below     7.2.27, 7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is     possible to supply data that will cause function     mbfl_filt_conv_big5_wchar to read past the allocated     buffer. This may lead to information disclosure or     crash.(CVE-2020-7060)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15     and 7.4.x below 7.4.3, when using file upload     functionality, if upload progress tracking is enabled,     but session.upload_progress.cleanup is set to 0     (disabled), and the file upload fails, the upload     procedure would try to clean up data that does not     exist and encounter null pointer dereference, which     would likely lead to a crash.(CVE-2020-7062)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15     and 7.4.x below 7.4.3, when creating PHAR archive using     PharData::buildFromIterator() function, the files are     added with default permissions (0666, or all access)     even if the original files on the filesystem were with     more restrictive permissions. This may result in files     having more lax permissions than intended when such     archive is extracted.(CVE-2020-7063)

  - Format string vulnerability in the php_snmp_error     function in ext/snmp/snmp.c in PHP before 5.5.34, 5.6.x     before 5.6.20, and 7.x before 7.0.5 allows remote     attackers to execute arbitrary code via format string     specifiers in an SNMP::get call.(CVE-2016-4071)

  - The Phar extension in PHP before 5.5.34, 5.6.x before     5.6.20, and 7.x before 7.0.5 allows remote attackers to     execute arbitrary code via a crafted filename, as     demonstrated by mishandling of \0 characters by the     phar_analyze_path function in     ext/phar/phar.c.(CVE-2016-4072)

  - Multiple integer overflows in the mbfl_strcut function     in ext/mbstring/libmbfl/mbfl/mbfilter.c in PHP before     5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allow     remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via a crafted mb_strcut call.(CVE-2016-4073)

  - In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7,     ext/intl/msgformat/msgformat_parse.c does not restrict     the locale length, which allows remote attackers to     cause a denial of service (stack-based buffer overflow     and application crash) or possibly have unspecified     other impact within International Components for     Unicode (ICU) for C/C++ via a long first argument to     the msgfmt_parse_message function.(CVE-2017-11362)

  - When processing certain files, PHP EXIF extension in     versions 7.1.x below 7.1.29, 7.2.x below 7.2.18 and     7.3.x below 7.3.5 can be caused to read past allocated     buffer in exif_process_IFD_TAG function. This may lead     to information disclosure or crash.(CVE-2019-11036)

  - Function iconv_mime_decode_headers() in PHP versions     7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below     7.3.6 may perform out-of-buffer read due to integer     overflow when parsing MIME headers. This may lead to     information disclosure or crash.(CVE-2019-11039)

  - In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18     and 7.4.x below 7.4.6, when HTTP file uploads are     allowed, supplying overly long filenames or field names     could lead PHP engine to try to allocate oversized     memory storage, hit the memory limit and stop     processing the request, without cleaning up temporary     files created by upload request. This potentially could     lead to accumulation of uncleaned temporary files     exhausting the disk space on the target     server.(CVE-2019-11048)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13     and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as     terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths     that the code is allowed to access.(CVE-2019-11045)

  - When PHP EXIF extension is parsing EXIF information     from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and     7.4.0 it is possible to supply it with data what will     cause it to read past the allocated buffer. This may     lead to information disclosure or     crash.(CVE-2019-11047)

  - When PHP EXIF extension is parsing EXIF information     from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and     7.4.0 it is possible to supply it with data what will     cause it to read past the allocated buffer.

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive     using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all     access) even if the original files on the filesystem were with more restrictive permissions. This may     result in files having more lax permissions than intended when such archive is extracted. (CVE-2020-7063)

  - In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with     UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could     lead to memory corruption, crashes and potentially code execution. (CVE-2020-7065)

  - In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers()     with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it.
    This may cause some software to make incorrect assumptions about the target of the get_headers() and     possibly send some information to a wrong server. (CVE-2020-7066)

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

  - PHP is an HTML-embedded scripting language. PHP     attempts to make it easy for developers to write     dynamically generated web pages. PHP also offers     built-in database integration for several commercial     and non-commercial database management systems, so     writing a database-enabled webpage with PHP is fairly     simple. The most common use of PHP coding is probably     as a replacement for CGI scripts. The php package     contains the module (often referred to as mod_php)     which adds support for the PHP language to Apache HTTP     Server. Security Fix(es):A flaw was found in HAProxy     before 2.0.6. In legacy mode, messages featuring a     transfer-encoding header missing the 'chunked' value     were not being correctly rejected. The impact was     limited but if combined with the 'http-reuse always'     setting, it could be used to help construct an HTTP     request smuggling attack against a vulnerable component     employing a lenient parser that would ignore the     content-length header as soon as it saw a     transfer-encoding one (even if not entirely valid     according to the specification).(CVE-2017-16642)In PHP     before 5.6.32, 7.x before 7.0.25, and 7.1.x before     7.1.11, an error in the date extension's     timelib_meridian handling of 'front of' and 'back of'     directives could be used by attackers able to supply     date strings to leak information from the interpreter,     related to ext/date/lib/parse_date.c out-of-bounds     reads affecting the php_parse_date function. NOTE: this     is a different issue than     CVE-2017-11145.(CVE-2017-11145)ext/standard/var_unseria     lizer.re in PHP before 5.6.26 mishandles     object-deserialization failures, which allows remote     attackers to cause a denial of service (memory     corruption) or possibly have unspecified other impact     via an unserialize call that references a partially     constructed object.(CVE-2016-10397)Double free     vulnerability in the zend_ts_hash_graceful_destroy     function in zend_ts_hash.c in the Zend Engine in PHP     through 5.5.20 and 5.6.x through 5.6.4 allows remote     attackers to cause a denial of service or possibly have     unspecified other impact via unknown     vectors.(CVE-2016-7412)Oniguruma through 6.9.3, as used     in PHP 7.3.x and other products, has a heap-based     buffer over-read in str_lower_case_match in     regexec.c.(CVE-2019-19246)When PHP EXIF extension is     parsing EXIF information from an image, e.g. via     exif_read_data() function, in PHP versions 7.2.x below     7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to     supply it with data what will cause it to read past the     allocated buffer. This may lead to information     disclosure or     crash.(CVE-2019-11047)main/php_open_temporary_file.c in     PHP before 5.5.28 and 5.6.x before 5.6.12 does not     ensure thread safety, which allows remote attackers to     cause a denial of service (race condition and heap     memory corruption) by leveraging an application that     performs many temporary-file     accesses.(CVE-2017-7272)When PHP EXIF extension is     parsing EXIF information from an image, e.g. via     exif_read_data() function, in PHP versions 7.2.x below     7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to     supply it with data what will cause it to read past the     allocated buffer. This may lead to information     disclosure or crash.(CVE-2019-11050)An issue was     discovered in Oniguruma 6.x before 6.9.4_rc2. In the     function fetch_interval_quantifier (formerly known as     fetch_range_quantifier) in regparse.c, PFETCH is called     without checking PEND. This leads to a heap-based     buffer     over-read.(CVE-2019-19204)main/streams/xp_socket.c in     PHP 7.x before 2017-03-07 misparses fsockopen calls,     such as by interpreting fsockopen('127.0.0.1:80', 443)     as if the address/port were 127.0.0.1:80:443, which is     later truncated to 127.0.0.1:80. This behavior has a     security risk if the explicitly provided port number     (i.e., 443 in this example) is hardcoded into an     application as a security policy, but the hostname     argument (i.e., 127.0.0.1:80 in this example) is     obtained from untrusted input.(CVE-2017-7189)

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

  - When PHP EXIF extension is parsing EXIF information     from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and     7.4.0 it is possible to supply it with data what will     cause it to read past the allocated buffer. This may     lead to information disclosure or     crash.(CVE-2019-11050)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13     and 7.4.0, PHP bcmath extension functions on some     systems, including Windows, can be tricked into reading     beyond the allocated space by supplying it with string     containing characters that are identified as numeric by     the OS but aren't ASCII numbers. This can read to     disclosure of the content of some memory     locations.(CVE-2019-11046)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13     and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as     terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths     that the code is allowed to access.(CVE-2019-11045)

  - When PHP EXIF extension is parsing EXIF information     from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and     7.4.0 it is possible to supply it with data what will     cause it to read past the allocated buffer. This may     lead to information disclosure or     crash.(CVE-2019-11047)

  - PHP through 7.1.11 enables potential SSRF in     applications that accept an fsockopen or pfsockopen     hostname argument with an expectation that the port     number is constrained. Because a :port syntax is     recognized, fsockopen will use the port number that is     specified in the hostname argument, instead of the port     number in the second argument of the     function.(CVE-2017-7272)

  - Oniguruma before 6.9.3 allows Stack Exhaustion in     regcomp.c because of recursion in     regparse.c.(CVE-2019-16163)

  - Oniguruma through 6.9.3, as used in PHP 7.3.x and other     products, has a heap-based buffer over-read in     str_lower_case_match in regexec.c.(CVE-2019-19246)

  - An issue was discovered in Oniguruma 6.x before     6.9.4_rc2. In the function fetch_interval_quantifier     (formerly known as fetch_range_quantifier) in     regparse.c, PFETCH is called without checking PEND.
    This leads to a heap-based buffer     over-read.(CVE-2019-19204)

  - An out-of-bounds read vulnerability was found in     Oniguruma in the way it handled regular expression     quantifiers. A remote attacker could abuse this flaw by     providing a malformed regular expression that, when     processed by an application linked to Oniguruma, could     possibly crash the application, resulting in a denial     of service.(CVE-2019-19204)

According to the versions of the oniguruma package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Oniguruma before 6.9.3 allows Stack Exhaustion in     regcomp.c because of recursion in     regparse.c.(CVE-2019-16163)

  - An issue was discovered in Oniguruma 6.x before     6.9.4_rc2. In the function gb18030_mbc_enc_len in file     gb18030.c, a UChar pointer is dereferenced without     checking if it passed the end of the matched string.
    This leads to a heap-based buffer     over-read.(CVE-2019-19203)

  - An issue was discovered in Oniguruma 6.x before     6.9.4_rc2. In the function fetch_interval_quantifier     (formerly known as fetch_range_quantifier) in     regparse.c, PFETCH is called without checking PEND.
    This leads to a heap-based buffer     over-read.(CVE-2019-19204)

  - Oniguruma through 6.9.3, as used in PHP 7.3.x and other     products, has a heap-based buffer over-read in     str_lower_case_match in regexec.c.(CVE-2019-19246)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in the Oniguruma regular expressions library, notably used in PHP mbstring.

CVE-2019-19012

An integer overflow in the search_in_range function in regexec.c leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial of service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression.

CVE-2019-19204

In the function fetch_range_quantifier in regparse.c, PFETCH is called without checking PEND. This leads to a heap-based buffer over-read and lead to denial of service via a crafted regular expression.

CVE-2019-19246

Heap-based buffer over-read in str_lower_case_match in regexec.c can lead to denial of service via a crafted regular expression.

For Debian 8 'Jessie', these problems have been fixed in version 5.9.5-3.2+deb8u4.

We recommend that you upgrade your libonig packages.
