  <description>This update for apache2 fixes the following issues:

* CVE-2018-1283:  when mod_session is configured to forward its session data to CGI applications 
                    (SessionEnv on, not the default), a remote user may influence their content by 
                    using a \"Session\" header leading to unexpected behavior [bsc#1086814].

* CVE-2018-1301: due to an out of bound access after a size limit being reached by reading the HTTP header, 
                   a specially crafted request could lead to remote denial of service. [bsc#1086817]
  
  * CVE-2018-1303: a specially crafted HTTP request header could lead to crash due to an out of bound read 
                   while preparing data to be cached in shared memory.[bsc#1086813]
  
  * CVE-2017-15715: a regular expression could match '$' to a newline character in a malicious filename, 
                    rather than matching only the end of the filename. leading to corruption of uploaded files.[bsc#1086774]
  
  * CVE-2018-1312: when generating an HTTP Digest authentication challenge, the nonce sent 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. [bsc#1086775]
  
  * CVE-2017-15710: mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, 
                    uses the Accept-Language header value to lookup the right charset encoding when verifying the 
                    user's credentials. If the header value is not present in the charset conversion table, 
                    a fallback mechanism is used to truncate it to a two characters value to allow a quick retry 
                    (for example, 'en-US' is truncated to 'en'). 
                    A header value of less than two characters forces an out of bound write of one NUL byte to a 
                   memory location that is not part of the string. In the worst case, quite unlikely, the process 
                   would crash which could be used as a Denial of Service attack. In the more likely case, this memory 
                   is already reserved for future use and the issue has no effect at all. [bsc#1086820]
  
 * gensslcert: fall back to 'localhost' as hostname [bsc#1057406]
