Title: PHP Zip_Entry_Read() Integer Overflow Vulnerability
Severity: HIGH
Description:
PHP is a general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
PHP is prone to an integer-overflow vulnerability because it fails to ensure that integer values aren't overrun.
Specifically, the vulnerability resides in the 'zip_read_entry()' function that is used to read file contents inside ZIP archives. The affected function fails to properly check and validate the length parameter. An attacker may exploit this issue by supplying a length value of '0xffffffff', causing a memory block of size zero to be allocated while allowing up to 4GB of data to be copied into this space. This will cause memory to be overwritten and corrupted. The wraparound occurs because '1' is added to the '0xffffffff' value to create room for a trailing NULL byte prior to the memory allocation.
Exploiting this issue may allow attackers to execute arbitrary machine code in the context of the affected application. Failed exploit attempts will likely result in a denial-of-service condition.
This issue affects versions prior to PHP 4.4.5.
