Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code or a timing attack on cryptographic keys.

For Debian 8 Jessie, these problems have been fixed in version 68.9.0esr-1~deb8u2.

Note: 68.9.0esr-1~deb8u2 fixes an i386 build error in the otherwise identical 68.9.0esr-1~deb8u1 that was uploaded but not announced.
