CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in PHP up to 4.3.10/5.0.3 (Programming Language Software). This issue affects the function pack. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

The weakness was published 12/16/2004 by Stefan Esser with isec (Website). It is possible to read the advisory at php.net. The identification of this vulnerability is CVE-2004-1018 since 11/04/2004. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

The exploit is available at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
