Updated apache packages fix security vulnerabilities

Publication date: 24 Aug 2017
Type: security
Affected Mageia releases : 6
CVE: CVE-2017-9788 , CVE-2017-9789


In Apache httpd before 2.4.27, the value placeholder in
[Proxy-]Authorization headers of type 'Digest' was not initialized or
reset before or between successive key=value assignments by
mod_auth_digest. Providing an initial key with no '=' assignment could
reflect the stale value of uninitialized pool memory used by the prior
request, leading to leakage of potentially confidential information, and
a segfault in other cases resulting in denial of service

When under stress, closing many connections, the HTTP/2 handling code in
Apache httpd 2.4.26 would sometimes access memory after it has been
freed, resulting in potentially erratic behavior (CVE-2017-9789).
