SUSE SLES12 Security Update : Recommended update for apache2 (SUSE-SU-2018:0261-1)

high Nessus Plugin ID 106471

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for apache2 fixes several issues. These security issues were fixed :

- CVE-2017-9789: When under stress (closing many connections) the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour (bsc#1048575).

- CVE-2017-7659: A maliciously constructed HTTP/2 request could cause mod_http2 to dereference a NULL pointer and crash the server process (bsc#1045160).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
