USN-2952-1 fixed vulnerabilities in PHP. One of the backported patches caused a regression in the PHP Soap client. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that the PHP Zip extension incorrectly handled directories when processing certain zip files. A remote attacker could possibly use this issue to create arbitrary directories.
(CVE-2014-9767)

It was discovered that the PHP Soap client incorrectly validated data types. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-8835, CVE-2016-3185)

It was discovered that the PHP MySQL native driver incorrectly handled TLS connections to MySQL databases. A man in the middle attacker could possibly use this issue to downgrade and snoop on TLS connections. This vulnerability is known as BACKRONYM. (CVE-2015-8838)

It was discovered that PHP incorrectly handled the imagerotate function. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly obtain sensitive information. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 15.10.
(CVE-2016-1903)

According to its self-reported version number, the remote pfSense install is prior to 2.2.4. It is, therefore, affected by multiple vulnerabilities as stated in the referenced vendor advisories.

According to its banner, the version of PHP 5.5.x running on the remote web server is prior to 5.5.27. It is, therefore, affected by multiple vulnerabilities :

  - A security feature bypass vulnerability, known as     'BACKRONYM', exists due to a failure to properly enforce     the requirement of an SSL/TLS connection when the --ssl     client option is used. A man-in-the-middle attacker can     exploit this flaw to coerce the client to downgrade to     an unencrypted connection, allowing the attacker to     disclose data from the database or manipulate database     queries. (CVE-2015-3152)

  - A flaw in the phar_convert_to_other function in     ext/phar/phar_object.c could allow a remote attacker     to cause a denial of service. (CVE-2015-5589)

  - A Stack-based buffer overflow in the phar_fix_filepath     function in ext/phar/phar.c could allow a remote attacker     to cause a denial of service. (CVE-2015-5590)

  - A flaw exists in the PHP Connector/C component due to a     failure to properly enforce the requirement of an     SSL/TLS connection when the --ssl client option is used.
    A man-in-the-middle attacker can exploit this to     downgrade the connection to plain HTTP when HTTPS is     expected. (CVE-2015-8838)

  - An unspecified flaw exists in the     phar_convert_to_other() function in phar_object.c during     the conversion of invalid TAR files. An attacker can     exploit this flaw to crash a PHP application, resulting     in a denial of service condition.

  - The '!' character is not treated as a special character     when delayed variable substitution is enabled. The     functions escapeshellcmd() and escapeshellarg() are     unable to properly sanitize arguments containing '!'.
    An attacker can exploit this to execute arbitrary     commands.

  - A double-free flaw exists in zend_vm_execute.h due to     improper handling of certain code. An attacker can     exploit this flaw to crash a PHP application, resulting     in a denial of service condition.

  - A flaw exists in the parse_ini_file() and     parse_ini_string() functions due to improper handling of     strings that contain a line feed followed by an escape     character. An attacker can exploit this to crash a PHP     application, resulting in a denial of service condition.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - ext/mysqlnd/mysqlnd.c in PHP before 5.4.43, 5.5.x     before 5.5.27, and 5.6.x before 5.6.11 uses a client     SSL option to mean that SSL is optional, which allows     man-in-the-middle attackers to spoof servers via a     cleartext-downgrade attack, a related issue to     CVE-2015-3152.(CVE-2015-8838)

  - In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14     and 8.0.0, when validating URL with functions like     filter_var($url, FILTER_VALIDATE_URL), PHP will accept     an URL with invalid password as valid URL. This may     lead to functions that rely on URL being valid to     mis-parse the URL and produce wrong data as components     of the URL.(CVE-2020-7071)

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.

  - CVE-2016-2554: A NULL pointer dereference in     phar_get_fp_offset could lead to crashes. [bsc#968284]     Note: we do not ship the phar extension currently, so we     are not affected.

  - CVE-2016-3141: A use-after-free / double-free in the     WDDX deserialization could lead to crashes or potential     code execution. [bsc#969821]

  - CVE-2016-3142: An Out-of-bounds read in     phar_parse_zipfile() could lead to crashes. [bsc#971912]     Note: we do not ship the phar extension currently, so we     are not affected.

  - CVE-2014-9767: A directory traversal when extracting zip     files was fixed that could lead to overwritten files.
    [bsc#971612]

  - CVE-2016-3185: A type confusion vulnerability in     make_http_soap_request() could lead to crashes or     potentially code execution. [bsc#971611]
