openSUSE Security Update : apache2 (openSUSE-2012-132)
Medium Nessus Plugin ID 74555
SynopsisThe remote openSUSE host is missing a security update.
Description- httpd-2.2.x-bnc743743-CVE-2012-0053-server_protocol_c-cookie_exposure.diff addresses CVE-2012-0053: error responses can expose cookies when no custom 400 error code ErrorDocument is configured. [bnc#743743]
scoreboard corruption (shared mem segment) by child causes crash of privileged parent (invalid free()) during shutdown.
This is rated low impact. Notice:
https://svn.apache.org/viewvc?view=revision&revision=1230065 makes a change to the struct global_score, which causes binary incompatibility. The change in above patch only goes as far as the binary compatibility allows; the vulnerability is completely fixed, though. CVE-2012-0031 [bnc#741243]
- /etc/init.d/apache2: new argument 'check-reload'. Exits 1 if httpd2 runs on deleted binaries such as after package update, else 0. This is used by equally modified /etc/logrotate.d/apache2, which uses '/etc/init.d/apache2 check-reload' in its prerotate script. These changes prevent httpd2 from being (gracefully) reloaded by logrotate, executed by cron, if new binaries have been installed. Instead, a warning is printed on stdout and is being logged to the syslogs. If this happens, apache's logs are NOT rotated, and the running processes are left untouched. This limits the maximum damage of log rotation to unrotated logs.
'/etc/init.d/apache2 restart' (or 'rcapache2 restart') must be executed manually in such a case. [bnc#728876]
- httpd-2.2.x-bnc729181-CVE-2011-3607-int_overflow.diff: Fix for integer overflow in server/util.c also known as CVE-2011-3607.
- enable build and configuration of mod_reqtimeout.c module by default in /etc/sysconfig/apache2 (APACHE_MODULES=...). This does not change already existing sysconfig files, the module is only activated via sysconfig if this package is installed without pre-existing sysconfig file. See new file /etc/apache2/mod_reqtimeout.conf for configurables.
Helps against Slowloris.pl DoS vulnerability that consists of eating up request slots by very slowly submitting the request. Note that mod_reqtimeout limits requests based on a lower boundary of request speed, not an upper boundary! CVE-2007-6750 [bnc#738855].
