<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]
