Synopsis: New sendmail packages available which fix a local root exploit
Advisory ID: RHSA-2001:106-06

---------------------------------------------------------------------
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.
