    Summary
    =======
    
    The package subversion before version 1.11.1-1 is vulnerable to denial
    of service.
    
    Resolution
    ==========
    
    Upgrade to 1.11.1-1.
    
    # pacman -Syu "subversion>=1.11.1-1"
    
    The problem has been fixed upstream in version 1.11.1.
    
    Workaround
    ==========
    
    None.
    
    Description
    ===========
    
    A denial of service has been found in subversion versions prior to
    1.11.1, allowing a malicious SVN client to crash a remote server using
    mod_dav_svn by omitting the root path from a recursive directory
    listing request, causing mod_dav_svn to dereference an uninitialized
    pointer variable and crash the httpd worker process handling the
    request.
    
    Impact
    ======
    
    A remote attacker is able to crash the server by sending a specially
    crafted request.
