More information:

The NSS library is vulnerable to two security issues:

  • CVE-2017-5461

    Out-of-bounds write in Base64 encoding. This can trigger a crash (denial of service) and might be exploitable for code execution.

  • CVE-2017-5462

    A flaw in DRBG number generation where the internal state V does not correctly carry bits over.

For Debian 7 Wheezy, these problems have been fixed in version 2:3.26-1+debu7u3.

We recommend that you upgrade your nss packages.
