In August 2017, openssl.org released a security advisory detailing several security issues. The following vulnerabilities that may affect the TLS/SSL data-plane of ACOS devices reported in that advisory are addressed in this document.
|Item #||Vulnerability ID||Score Source||Score||Summary|
|1||CVE-2017-3735||CVSS 3.0||5.3 Med||openssl: Malformed X.509 IPAdressFamily could cause OOB read|
The table below indicates releases of ACOS exposed to these vulnerabilities and ACOS releases that address them. ACOS release families not indicated below are unaffected by these vulnerabilities.
Customers using affected ACOS releases can overcome vulnerability exposures by updating to the indicated resolved release. If the table does not list a corresponding resolved or unaffected release, then no ACOS release update is currently available.
|Releases Affected||Releases Resolved or Unaffected|
4.1.2 – 4.1.2-P2
4.1.1 – 4.1.1-P5
4.1.0 – 4.1.0-P9

The following table shares brief descriptions of the vulnerabilities addressed in this document.
|Vulnerability ID||Vulnerability Description|
If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. The most likely result would be an erroneous display of the certificate in text format.
As this is a low severity fix, no release is being made. The fix can be found in the source repository (1.0.2, 1.1.0, and master branches); see https://github.com/openssl/openssl/pull/4276. This bug has been present since 2006.
