A vulnerability has been discovered in nss, the Mozilla Network Security Service library. An out-of-bounds write can occur when passing an output buffer smaller than the block size to NSC_EncryptUpdate.
For Debian 7 Wheezy, these problems have been fixed in version 2:3.26-1+debu7u9.
We recommend that you upgrade your nss packages.
