openSUSE Security Update : apache2 (openSUSE-2018-104)

high Nessus Plugin ID 106523

Language:

Synopsis

The remote openSUSE host is missing a security update.

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).

These non-security issues were fixed :

 - Use the full path to a2enmod and a2dismod in the apache-22-24-upgrade script (bsc#1042037)

 - Fall back to 'localhost' as hostname in gensslcert (bsc#1057406)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

Solution

Update the affected apache2 packages.
