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

Description

The 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.

Mitigation

Update the affected packages.
dev-db/redis to version: 4.0.14

Vulnerable software versions

Gentoo Linux: All versions

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

Description

The 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.

Mitigation

Update the affected packages.
dev-db/redis to version: 4.0.14

3) 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

Description

The 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.

Mitigation

Update the affected packages.
dev-db/redis to version: 4.0.14
