5) Input validation error

EUVDB-ID: #VU40292

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2014-9771

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (memory consumption or application crash) via a crafted image, which triggers an invalid read operation.
