Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU13380
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-11218
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to stack-based buffer overflow in the cmsgpack library in the Lua subsystem. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash.
MitigationInstall updates from vendor's website.
rh-redis32-redis (Red Hat package): before 3.2.13-1.el6
CPE2.3 External linkshttps://access.redhat.com/errata/RHSA-2019:1860
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Integer overflow
EUVDB-ID: #VU13381
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-11219
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to integer overflow in the struct library in the Lua subsystem. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash.

3) Buffer overflow
EUVDB-ID: #VU13401
Risk: Low
CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/U:Clear]
CVE-ID: CVE-2018-12326
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The vulnerability exists due to a buffer overflow condition in the redis-clicomponent. A local attacker can execute a specially crafted command that submits malicious input, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationInstall updates from vendor's website.
rh-redis32-redis (Red Hat package): before 3.2.13-1.el6
CPE2.3 External linkshttps://access.redhat.com/errata/RHSA-2019:1860
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
4) Heap-based buffer overflow
EUVDB-ID: #VU19167
Risk: Medium
CVSSv4.0: 5.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-10192
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing Redis hyperloglog data structure. A remote attacker can carefully corrupt hyperloglog using the SETRANGE command, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
