2) Input validation error

EUVDB-ID: #VU24196

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-11213

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input within the get_text_gray_row() function in rdppm.c. A remote attacker can create a specially crafted image, trick the victim into opening it with software that uses the affected version of libjpeg, and perform a denial of service attack.

Mitigation

Update the affected package libjpeg6b to the latest version.
