From: bugzilla@redhat.com To: redhat-watch-list@redhat.com Subject: [RHSA-2001:106-06] New sendmail packages available which fix a local root exploit Date: Mon, 10 Sep 2001 12:08 -0400 Cc: bugtraq@securityfocus.com, linux-security@redhat.com --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: New sendmail packages available which fix a local root exploit Advisory ID: RHSA-2001:106-06 Issue date: 2001-08-28 Updated on: 2001-09-06 Product: Red Hat Linux Keywords: sendmail local root input validation debug smtp mta Cross references: Obsoletes: --------------------------------------------------------------------- 1. Topic: An input validation error in the debugging functionality of all currently released versions of sendmail can enable a local user to gain root access. New packages that fix this problem are available for Red Hat Linux 5.2, 6.2, 7.0, and 7.1. 2. Relevant releases/architectures: Red Hat Linux 5.2 - alpha, i386, sparc Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 3. Problem description: Sendmail, the low-level system for sending and receiving email for Red Hat Linux, has an input validation flaw in part of its debugging code. This flaw could be exploited by an attacker who already has local access to a system and wants to gain root privileges. Red Hat is issuing new sendmail packages that correct this flaw for all our currently supported Red Hat Linux platforms. All users are strongly advised to apply these fixes. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this to be an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
