    (CVE-2016-4542)

  - A flaw exists in PHP in the exif_process_IFD_in_JPEG()     function in exif.c due to improper validation of IFD     sizes. An unauthenticated, remote attacker can exploit     this, via crafted header data, to cause an out-of-bounds     read error, resulting in a denial of service condition     or the disclosure of memory contents. (CVE-2016-4543)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', in the Apache Tomcat, Apache HTTP Server, and     PHP components due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. A remote attacker can exploit this, via a     crafted 'Proxy' header in an HTTP request, to redirect     an application's internal HTTP traffic to an arbitrary     proxy server where it may be observed or manipulated.
    (CVE-2016-5385, CVE-2016-5387, CVE-2016-5388)

It was discovered that PHP incorrectly handled certain malformed EXIF tags. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2016-4542, CVE-2016-4543, CVE-2016-4544).

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

This update for libqt5-qtbase fixes the following issues :

  - boo#865241: disable RC4 based ciphers which are now     considered insecure

The following non-security bugs were fixed :

  - boo#957006: dolphin freeze when opening a folder     containing symlinks to special files

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.3. It is, therefore, affected by multiple vulnerabilities :

  - The Perl-Compatible Regular Expressions (PCRE) library     is affected by multiple vulnerabilities related to the     handling of regular expressions, subroutine calls, and     binary files. A remote attacker can exploit these to     cause a denial of service, obtain sensitive information,     or have other unspecified impact. (CVE-2015-8383,     CVE-2015-8386, CVE-2015-8387, CVE-2015-8389,     CVE-2015-8390, CVE-2015-8391, CVE-2015-8393,     CVE-2015-8394)

  - A flaw exists in file ext/standard/exec.c in the     escapeshellcmd() and escapeshellarg() functions due to     the program truncating NULL bytes in strings. A remote     attacker can exploit this to bypass restrictions.

  - A flaw exists in file ext/standard/streamsfuncs.c in the     stream_get_meta_data() function due to a failure to     restrict writing user-supplied data to fields not     already set. A remote attacker can exploit this to     falsify the output of the function, resulting in the     insertion of malicious metadata.

  - A type confusion error exists in file ext/wddx/wddx.c in     the php_wddx_pop_element() function when deserializing     WDDX packets. A remote attacker can exploit this to have     an unspecified impact.

  - A flaw exists in file ext/phar/phar_object.c in the     PharFileInfo::getContent() method due to the use of     uninitialized memory causing improper validation of     user-supplied input. A remote attacker can exploit this     to corrupt memory, resulting in a denial of service or     the execution of arbitrary code.

  - A NULL pointer dereference flaw exists in file     ext/phar/tar.c in the phar_tar_setupmetadata() function     when parsing metadata from a crafted TAR file. A remote     attacker can exploit this to cause a denial of service.

  - An integer overflow condition exists in file     ext/standard/iptc.c in the iptcembed() function due to     improper validation of user-supplied input. A remote     attacker can exploit this to cause a heap-based buffer     overflow, resulting in a denial of service or the     execution of arbitrary code.

  - An overflow condition exists in file ext/phar/tar.c in     the phar_parse_tarfile() function due to improper     validation of user-supplied input when decompressing     TAR files. A remote attacker can exploit this to cause     a stack-based buffer overflow, resulting in a denial of     service or the execution of arbitrary code.
    (CVE-2016-2554)

  - An uninitialized pointer flaw exists in the     phar_make_dirstream() function within file     ext/phar/dirstream.c due to improper handling of     ././@LongLink files. An unauthenticated, remote attacker     can exploit this, via a specially crafted TAR file, to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-4343)

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

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.18. It is, therefore, affected by multiple vulnerabilities :
