Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU26105
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-18508
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in Mozilla NSS within the CMS (Cryptographic Message Syntax) API. A remote attacker can perform a denial of service (DoS) attack.
MitigationUpdate the affected packages.
Opensuse: 15.1
External linkshttp://lists.opensuse.org/opensuse-security-announce/2020-01/msg00006.html
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) Improper Certificate Validation
EUVDB-ID: #VU47195
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-11727
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists doe to an error within the Mozilla NSS library, when working with TLS certificates. A remote attacker can force Network Security Services (NSS) to sign CertificateVerify with
PKCS#1 v1.5 signatures when those are the only ones advertised by server
in CertificateRequest in TLS 1.3. A remote attacker can perform a Man-in-the-Middle attack and gain access to sensitive information.
Update the affected packages.

3) Out-of-bounds write
EUVDB-ID: #VU23050
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-11745
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the NSC_EncryptUpdate() function in /lib/softoken/pkcs11c.c, when performing padding operations in Mozilla NSS. A remote attacker can pass specially crafted data to the affected application, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate the affected packages.

4) Heap-based buffer overflow
EUVDB-ID: #VU47197
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-17006
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 in Mozilla NSS library when processing input text length while using certain cryptographic primitives. A remote attacker can pass specially crafted data to the application, 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.
MitigationUpdate the affected packages.
