  From:  To:  Subject: [RHSA-2001:106-06] New sendmail packages available which fix a local root exploit  Date:     Mon, 10 Sep 2001 12:08 -0400  Cc:,    ---------------------------------------------------------------------                     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. Bug IDs fixed ( for more info):    52194 - SUID sendmail allows local overflow    6.
