Slackware Linux Advisories: openssh, sendmail

Sep 17, 2003, 20:41 (0 Talkback[s])

[slackware-security] OpenSSH updated again (SSA:2003-260-01)

Upgraded OpenSSH 3.7.1p1 packages are available for Slackware 8.1, 9.0 and -current. These fix additional buffer management errors that were not corrected in the recent 3.7p1 release. The possibility exists that these errors could allow a remote exploit, so we recommend all sites running OpenSSH upgrade to the new OpenSSH package immediately.

Here are the details from the Slackware 9.0 ChangeLog:


Wed Sep 17 01:25:22 PDT 2003
patches/packages/openssh-3.7.1p1-i386-1.tgz: Upgraded to openssh-3.7.1p1.
The OpenSSH advisory was updated (http://www.openssh.com/txt/buffer.adv) and now says that you need at least version 3.7.1, which fixes some more buffer problems like those fixed by 3.7.
(* Security fix *)

[slackware-security] Sendmail vulnerabilities fixed (SSA:2003-260-02)

The sendmail packages in Slackware 8.1, 9.0, and -current have been patched to fix security problems. These issues seem to be remotely exploitable, so all sites running sendmail should upgrade right away.

Sendmail's 8.12.10 announcement may be found here: http://www.sendmail.org/8.12.10.html

Here are the details from the Slackware 9.0 ChangeLog:



Wed Sep 17 10:10:26 PDT 2003
patches/packages/sendmail-8.12.10-i386-1.tgz: Upgraded to sendmail-8.12.10. This fixes security issues as noted in Sendmail's RELEASE_NOTES:
"SECURITY: Fix a buffer overflow in address parsing. Problem detected by Michal Zalewski, patch from Todd C. Miller of Courtesan Consulting.
Fix a potential buffer overflow in ruleset parsing. This problem is not exploitable in the default sendmail configuration; only if non-standard rulesets recipient (2), final (4), or mailer-specific envelope recipients rulesets are used then a problem may occur. Problem noted by Timo Sirainen."

We recommend that sites running Sendmail upgrade immediately.
