An update that solves 6 vulnerabilities and has one errata
is now available.

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]
