Issues
| CVE-2016-1978 | |
|---|---|
| Severity / CVSSv2 | Medium / 6.8 (AV:N/AC:M/Au:N/C:P/I:P/A:P) |
| References | SecurityFocus: BID 84275 / NVD: CVE-2016-1978 |
| Impact | Denial of service, code execution |
| Description | A use-after-free flaw in the SSL/TLS client implementation for DHE and ECDHE cipher suites allows a remote attacker to cause application crashes resulting in denial of service. The attacker may also execute arbitrary code with the permission of the user running the NSS SSL/TLS client application. |
| CVE-2016-1979 | |
|---|---|
| Severity / CVSSv2 | Medium / 6.8 (AV:N/AC:M/Au:N/C:P/I:P/A:P) |
| References | SecurityFocus: BID 84221 / NVD: CVE-2016-1979 |
| Impact | Denial of service, code execution |
| Description | A use-after-free flaw in DER encoded private key parsing allows a remote attacker to cause application crashes resulting in denial of service. The attacker may also execute arbitrary code with the permissions of the user running the NSS application. |
Mitigation
CVE-2016-1979 can be exploited in affected products only through their management interfaces. Allowing only machines, IP addresses and subnets from a trusted network to access the management interface reduces the threat of exploiting the vulnerabilities.
