Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU15334
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-18227
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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 MS-WSP dissector component to crash.
MitigationThe vulnerability has been addressed in the version 2.4.10, 2.6.4.
Vulnerable software versionsWireshark: 2.4.0 - 2.6.3

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Memory leak
EUVDB-ID: #VU15335
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-18226
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe 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.
MitigationThe vulnerability has been addressed in the version 2.6.4.
Vulnerable software versionsWireshark: 2.6.0 - 2.6.3
