DATE CVE VULNERABILITY TITLE RISK
2016-09-12 CVE-2016-7126 Out-of-bounds Write vulnerability in PHP
The imagetruecolortopalette function in ext/gd/gd.c in PHP before 5.6.25 and 7.x before 7.0.10 does not properly validate the number of colors, which allows remote attackers to cause a denial of service (select_colors allocation error and out-of-bounds write) or possibly have unspecified other impact via a large value in the third argument.

2016-09-12 CVE-2016-7125 Injection vulnerability in PHP
ext/session/session.c in PHP before 5.6.25 and 7.x before 7.0.10 skips invalid session names in a way that triggers incorrect parsing, which allows remote attackers to inject arbitrary-type session data by leveraging control of a session name, as demonstrated by object injection.

2016-09-12 CVE-2016-7124 Deserialization of Untrusted Data vulnerability in PHP
ext/standard/var_unserializer.c in PHP before 5.6.25 and 7.x before 7.0.10 mishandles certain invalid objects, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that leads to a (1) __destruct call or (2) magic method call.

2016-08-12 CVE-2016-6207 Integer Overflow or Wraparound vulnerability in multiple products
Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors.

2016-08-07 CVE-2016-5773 Use After Free vulnerability in PHP
php_zip.c in the zip extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) via crafted serialized data containing a ZipArchive object.

2016-07-25 CVE-2016-6297 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in PHP
Integer overflow in the php_stream_zip_opener function in ext/zip/zip_stream.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a crafted zip:// URL.

2016-07-25 CVE-2016-6296 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in PHP
Integer signedness error in the simplestring_addn function in simplestring.c in xmlrpc-epi through 0.54.2, as used in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9, allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a long first argument to the PHP xmlrpc_encode_request function.

2016-07-25 CVE-2016-6294 Out-of-bounds Read vulnerability in PHP
The locale_accept_from_http function in ext/intl/locale/locale_methods.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 does not properly restrict calls to the ICU uloc_acceptLanguageFromHTTP function, which allows 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.
