It was found that certain cryptographic primitives in nss, the Network Security Service libraries, did not check the length of the input text. This could result in a potential heap-based buffer overflow.

For Debian 8 Jessie, this problem has been fixed in version 2:3.26-1+debu8u10.

We recommend that you upgrade your nss packages.
