Description Mark J. Cox 2004-06-02 12:12:48 UTC 
A stack-based buffer overflow in the ssl_util_uuencode_binary
function in ssl_util.c for Apache mod_ssl when mod_ssl is
configured to trust the issuing CA, and "FakeBasicAuth" is
being used, could allow remote attackers to execute arbitrary
code via a client certificate with a long subject DN.  Public
to full-disclosure on 17May.  Fixed Apache 2 CVS 25May

It is quite unlikely that users will have a vulnerable configuration
of Apache, therefore this is of low risk.

        CAN-2004-0488 Affects: FC1
        CAN-2004-0488 Affects: FC2
Comment 1 Robert Scheck 2004-06-15 06:06:38 UTC 
Joe, can we please get the fix for mod_ssl: security fix for overflow 
in FakeBasicAuth (CVE CAN-2004-0488), for FC1 and 2 which is already 
available in 2.0.49-5? I also can find a package fixing this 
vulnerability in a public testing tree...
