-----BEGIN PGP SIGNED MESSAGE----- On Friday, Oct. 30th, IBM-ERS sent out a draft advisory to be released on Monday, Nov. 2nd that described a buffer overflow condition in Version 1.2.x "sshd." This draft was sent to the Forum of Incident Response and Security Teams, and also to the "ssh-bugs" list for their comment/review. The draft was identified as ERS-SVA-E01-1998:005.1. Rootshell has unfortunately chosen to include a copy of this draft advisory in their recent newsletter, apparently for the purposes of defending itself against charges that it was unfairly disparaging "sshd." Use of IBM-ERS's draft advisory in this manner was not approved or authorized by IBM-ERS, and does a disservice to all. Here are the facts about this advisory: 1. IBM-ERS advisory ERS-SVA-E01-1998:005.1 was never issued publicly by IBM. 2. In response to a telephone query from Kit Knox of Rootshell, IBM-ERS attempted to contact Kit on Friday evening, and was unable to reach him. Specific contact information for IBM-ERS, as well as a brief status update, were left on Mr. Knox's voice mail. Mr. Knox never contacted IBM-ERS after that time. 3. IBM has been working closely with Tatu Ylonen, author of "ssh," to make sure that the potential vulnerability described in the advisory is not exploitable. Upon further investigation, the problem originally described appears to have been influenced by outside factors and does not appear to be an exploitable problem in "sshd." 4. IBM-ERS advisory ERS-SVA-E01-1998:005.1 was CANCELLED on the morning of Sunday, Nov. 1st, *before* Mr. Knox issued his newsletter. 5. At this time, IBM-ERS has NO KNOWLEDGE of any security vulnerabilities, exploitable or otherwise, in the "sshd" program. We hope that this clarifies IBM's involvement in this situation. - --------------------------------------------------------------------------- The information in this document is provided as a service to customers of the IBM Emergency Response Service.
