Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU7187
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-2780
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 in the X509 certificate parsing functionality of InsideSecure MatrixSSL due to heap-based buffer overflow. A remote attacker can supply a specially crafted x509 certificate when initiating secure connection, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
MitigationUpdate to version 3.9.3.
MatrixSSL: 3.8.7 b

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) Information disclosure
EUVDB-ID: #VU7198
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-2782
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The vulnerability exists in the X509 certificate parsing functionality of InsideSecure MatrixSSL due to length counter overflow. A remote attacker can supply a specially crafted x509 certificate when initiating secure connection, perform out of bounds copy operation, trigger memory leak and read arbitrary files.
Successful exploitation of the vulnerability results in information disclosure.
MitigationUpdate to version 3.9.3.
MatrixSSL: 3.8.7 b

3) Heap-based buffer overflow
EUVDB-ID: #VU7197
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-2781
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 in the 'parsePolicyMappings' function in MatrixSSL due to heap-based buffer overflow when parsing the IssuerPolicy PolicyMappings extension. A remote attacker can supply a specially crafted x509 certificates in DER format containing OID value, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
Update to version 3.9.3.
MatrixSSL: 3.8.7 b
