    Synopsis
    ========
    
    A vulnerability in c-icap could result in Denial of Service.
    
    Background
    ==========
    
    c-icap is an implementation of an ICAP server. It can be used with HTTP
    proxies that support the ICAP protocol to implement content adaptation
    and filtering services.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-proxy/c-icap             < 0.2.6 >= 0.2.6
    
    Description
    ===========
    
    c-icap contains a flaw in the parse_request() function of request.c
    that may allow a remote denial of service. The issue is triggered when
    the buffer fails to contain a ' ' or '?' symbol, which will cause the
    end pointer to increase and surpass allocated memory. With a specially
    crafted request (e.g. via the OPTIONS method), a remote attacker can
    cause a loss of availability for the program.
    
    Impact
    ======
    
    A remote attacker may cause a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All c-icap users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-proxy/c-icap-0.2.6"
