Package : apache2 Version : 2.2.22-13+deb7u13 CVE ID : CVE-2017-15710 CVE-2018-1301 CVE-2018-1312 Debian Bug :
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.
