high Nessus Plugin ID 91365

Language:

Synopsis

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

Description

Two vulnerabilities were discovered in Symfony, a PHP framework.

- CVE-2016-1902 Lander Brandt discovered that the class SecureRandom might generate weak random numbers for cryptographic use under certain settings. If the functions random_bytes() or openssl_random_pseudo_bytes() are not available, the output of SecureRandom should not be consider secure.

- CVE-2016-4423 Marek Alaksa from Citadelo discovered that it is possible to fill up the session storage space by submitting inexistent large usernames.

Solution

Upgrade the symfony packages.

For the stable distribution (jessie), these problems have been fixed in version 2.3.21+dfsg-4+deb8u3.
