ISSUES
| CVE-2017-5461 | |
|---|---|
| Severity / CVSSv2 | High / 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P) |
| References | SecurityFocus: BID 98050 / NVD: CVE-2017-5461 |
| Impact | Denial of service, code execution |
| Description | An out-of-bounds write flaw in the Base64 encoder/decoder allows a remote attacker to send crafted Base64 data, such as an X.509 certificate, and cause denial of service through an application crash. The attacker could also execute arbitrary code with the permission of the application using NSS. |
MITIGATION
By default, Director, Security Analytics, and XOS do not use NSS to parse Base64 data from external sources. Customers who leave this behavior unchanged prevent attacks against these products using CVE-2017-5461.
CVE-2017-5461 only affects LDAPS client connections in PacketShaper S-Series and PolicyCenter S-Series. Deploying these products in a secure, trusted network reduces the threat of exploiting this vulnerability.
