Posted by Team   
RedHat Linux Pine did not allocate enough memory for the parsing and escaping of the "From" header, allowing a carefully crafted email to cause a buffer overflow on the heap.

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated pine packages available
Advisory ID:       RHSA-2002:270-16
Issue date:        2003-01-03
Updated on:        2003-01-02
Product:           Red Hat Linux
Keywords:          pine vulnerable DoS denial of service crash flaw:buf
Cross references:  
Obsoletes:         RHSA-2002:009
CVE Names:         CAN-2002-1320

1. Topic:

A vulnerability in Pine version 4.44 and earlier releases can cause
Pine to crash when sent a carefully crafted email.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - i386
Red Hat Linux 7.0 - i386
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386

3. Problem description:

Pine, developed at the University of Washington, is a tool for reading,
sending, and managing electronic messages (including mail and news).

A security problem was found in versions of Pine 4.44 and earlier. In these
versions, Pine does not allocate enough memory for the parsing and escaping
of the "From" header, allowing a carefully crafted email to cause a
buffer overflow on the heap. This will result in Pine crashing.

All users of Pine on Red Hat Linux are advised to update to these errata
packages containing a patch to version 4.44 of Pine that fixes this

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 an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed  (http://bugzilla.Red for more info):

78293 - Pine 4.44 has a buffer overflow in the From address processing code.

6. RPMs required:

Red Hat Linux 6.2:



Red Hat Linux 7.0:



Red Hat Linux 7.1:



Red Hat Linux 7.2:




Red Hat Linux 7.3:



Red Hat Linux 8.0:
