                     CVE-2017-7679
    
    Several vulnerabilities have been found in the Apache HTTPD server.
    
    CVE-2017-3167
    
        Emmanuel Dreyfus reported that the use of ap_get_basic_auth_pw() by
        third-party modules outside of the authentication phase may lead to
        authentication requirements being bypassed.
    
    CVE-2017-3169
    
        Vasileios Panopoulos of AdNovum Informatik AG discovered that
        mod_ssl may dereference a NULL pointer when third-party modules call
        ap_hook_process_connection() during an HTTP request to an HTTPS port
        leading to a denial of service.
    
    CVE-2017-7659
    
        Robert Swiecki reported that a specially crafted HTTP/2 request
        could cause mod_http2 to dereference a NULL pointer and crash the
        server process.
    
    CVE-2017-7668
    
        Javier Jimenez reported that the HTTP strict parsing contains a
        flaw leading to a buffer overread in ap_find_token(). A remote
        attacker can take advantage of this flaw by carefully crafting a
        sequence of request headers to cause a segmentation fault, or to
        force ap_find_token() to return an incorrect value.
    
    CVE-2017-7679
    
        ChenQin and Hanno Boeck reported that mod_mime can read one byte
        past the end of a buffer when sending a malicious Content-Type
        response header.
    
    For the oldstable distribution (jessie), these problems have been fixed
    in version 2.4.10-10+deb8u9. The oldstable distribution (jessie) is not
    affected by CVE-2017-7659.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 2.4.25-3+deb9u1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 2.4.25-4.
    
    We recommend that you upgrade your apache2 packages.
