Openwall GNU/*/Linux Information for VU#457875
| Date Notified | 10/29/2002 |
| Date Modified | 10/18/2004 11:01:49 AM |
| Status Summary | Vulnerable |
Vendor StatementOne of the features added with BIND 4.9.x-OW patches has always been the addition of unpredictable query IDs, thus making BIND 4 with these patches applied more resistant against the described attacks. The randomization of source port numbers is, however, currently left up to the operating system kernel (and thus doesn't occur on most systems). Future versions of the patches might add this functionality.
Similarly, the glibc resolver code on Openwall GNU/*/Linux (Owl) has been modified to use unpredictable query IDs (including in the very first version of Owl available to the public), but doesn't explicitly randomize source port numbers.US-CERT AddendumThe CERT/CC has no additional comments at this time.
If you have feedback, comments, or additional information about this vulnerability, please send us
