Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2016-1904)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple integer overflows in ext/standard/exec.c in PHP 7.x before 7.0.2 allow remote attackers to cause a denial of service or possibly have unspecified other impact via a long string to the (1) php_escape_shell_cmd or (2) php_escape_shell_arg function, leading to a heap-based buffer overflow.


2) Buffer overflow (CVE-ID: CVE-2016-1903)

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

The gdImageRotateInterpolated function in ext/gd/libgd/gd_interpolation.c in PHP before 5.5.31, 5.6.x before 5.6.17, and 7.x before 7.0.2 allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read and application crash) via a large bgd_color argument to the imagerotate function.


3) Format string error (CVE-ID: CVE-2015-8617)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Format string vulnerability in the zend_throw_or_error function in Zend/zend_execute_API.c in PHP 7.x before 7.0.1 allows remote attackers to execute arbitrary code via format string specifiers in a string that is misused as a class name, leading to incorrect error handling.
