  script_tag(name:"insight", value:"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]");
