Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU17698
Risk: Low
CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-16881
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the imptcp module due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted message to the imptcp socket that submits malicious input and cause the affected software to crash, resulting in a DoS condition.
MitigationUpdate the affected package rsyslog to the latest version.
Vulnerable software versionsUbuntu: 16.04
rsyslog (Ubuntu package): before 8.16.01u buntu3.1+esm1
