Synopsis

The remote Debian host is missing a security-related update.

Description

Several security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, use-after-frees, buffer overflows and other implementation errors may lead to the execution of arbitrary code, denial of service, bypass of the same-origin policy or incorrect enforcement of CSP.

Solution

Upgrade the firefox-esr packages.

For the oldstable distribution (jessie), these problems have been fixed in version 52.3.0esr-1~deb8u2.

For the stable distribution (stretch), these problems have been fixed in version 52.3.0esr-1~deb9u1.
