1) Improper input validation

EUVDB-ID: #VU10335

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-8923

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation in zend_string_extend() function in Zend/zend_string.h when leveraging a script's use of ".=" with a long. The application does not prevent changes to string objects that can result in a negative length. A remote attacker can pass an overly long string to script, which uses ".=" operand on the supplied data and trigger application crash.

Mitigation

Update the affected package php74 to the latest version.
