Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2017-2780)
The 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.
2) Information disclosure (CVE-ID: CVE-2017-2782)
The 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2017-2781)
The 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.
