Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU12642

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-10177

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the ReadOneMNGImage function of the coders/png.c file due to infinite loop. A remote attacker can trick the victim into opening a specially crafted mng file and cause the service to crash.

Mitigation

Install update from vendor's website.
