Debian DLA-1389-1 : apache2 security update
critical Nessus Plugin ID 110250
Language:
Synopsis
The remote Debian host is missing a security update.Description
Several vulnerabilities have been found in the Apache HTTPD server.CVE-2017-15710
Alex Nichols and Jakob Hirsch reported that mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, could cause an of bound write if supplied with a crafted Accept-Language header. This could potentially be used for a Denial of Service attack.
CVE-2018-1301
Robert Swiecki reported that a specially crafted request could have crashed the Apache HTTP Server, due to an out of bound access after a size limit is reached by reading the HTTP header. CVE-2018-1312
Nicolas Daniels discovered that when generating an HTTP Digest authentication challenge, the nonce sent by mod_auth_digest to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.
For Debian 7 'Wheezy', these problems have been fixed in version 2.2.22-13+deb7u13.
We recommend that you upgrade your apache2 packages.
