CVE-2016-1904
HighSummary
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 php_escape_shell_cmd or php_escape_shell_arg function, leading to a heap-based buffer overflow.
Risk Assessment
Attackers may exploit this vulnerability to disrupt the operation of PHP applications, potentially leading to service outages and further attacks.
Recommendation
It is recommended to upgrade PHP to version 7.0.2 or later to mitigate this vulnerability and to monitor applications for unauthorized activities.
Other vulnerabilities in PHP 7.x before 7.0.2
See all- CVE-2015-8616High
A use-after-free vulnerability in the Collator::sortWithSortKeys function in PHP 7.x before version 7.0.1 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging the relationships between a key buffer and a destroyed array.
- CVE-2015-6527High
The php_str_replace_in_subject function in PHP 7.x before 7.0.0 allows remote attackers to execute arbitrary code via a crafted value in the third argument to the str_ireplace function.
- CVE-2016-9936Critical
The unserialize implementation in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data.
- CVE-2016-3132Critical
A double free vulnerability in the SplDoublyLinkedList::offsetSet function in PHP 7.x before 7.0.6 allows remote attackers to execute arbitrary code via a crafted index.
- CVE-2015-8880Critical
A double free vulnerability in the format printer in PHP 7.x before 7.0.1 allows remote attackers to trigger an error, potentially leading to unspecified impact.
- CVE-2015-8617Critical
CVE-2015-8617 describes a format string vulnerability in the zend_throw_or_error function in PHP 7.x before version 7.0.1. This allows remote attackers to execute arbitrary code via format string specifiers in a string misused as a class name, leading to incorrect error handling.
Original NVD description (English source)
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.
