#VU110420 Input validation error in PHP - CVE-2007-1717

Vulnerability identifier: #VU110420

Vulnerability risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2007-1717

CWE-ID: CWE-20

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
PHP
Universal components / Libraries / Scripting languages

Vendor: PHP Group

Description

The vulnerability allows a remote non-authenticated attacker to corrupt data.

The mail function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 truncates e-mail messages at the first ASCIIZ ('') byte, which might allow context-dependent attackers to prevent intended information from being delivered in e-mail messages. NOTE: this issue might be security-relevant in cases when the trailing contents of e-mail messages are important, such as logging information or if the message is expected to be well-formed.

Mitigation
Install update from vendor's website.
