Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Improper input validation

EUVDB-ID: #VU15337

Risk: Low

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-12086

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and cause the OpcUa dissector component to crash.

Mitigation

Update the affected package wireshark-cli to version 2.6.4-1.

Vulnerable software versions

Arch Linux: All versions

3) Memory leak

EUVDB-ID: #VU15335

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-18226

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to memory leak in the Steam IHS Discovery dissector when handling malicious input. A remote attacker can inject a malformed packet into a network, to be processed by the affected application, or trick the victim into opening a malicious packet trace file and gain access to arbitrary data.

Mitigation

Update the affected package wireshark-cli to version 2.6.4-1.
