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 and other implementation errors may lead to the execution of arbitrary code, denial of service or bypass of the same origin policy.

Solution

Upgrade the firefox-esr packages.

For the oldstable distribution (jessie), these problems have been fixed in version 52.5.0esr-1~deb8u1.

For the stable distribution (stretch), these problems have been fixed in version 52.5.0esr-1~deb9u1.
