Description: A vulnerability was reported in Ethereal in the processing of RADIUS packet attributes. A remote user can cause the Ethereal process to crash.
Jonathan Heusser reported that a remote user can send a specially crafted packet to trigger a null pointer dereference, causing the
application to crash. The flaw reportedly resides in the dissect_attribute_value_pairs() function in the 'packet-radius.c' file.
The
report indicates that it may be possible to execute arbitrary code.

Mandrakelinux Security Update Advisory
_______________________________________________________________________
Package name: ethereal
Advisory ID: MDKSA-2004:024
Date: March 30th, 2004
Affected versions: 9.1, 9.2
______________________________________________________________________
Problem Description:
A number of serious issues have been discovered in versions of Ethereal
prior to 0.10.2. Stefan Esser discovered thirteen buffer overflows in
the NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP dissectors.
Jonathan Heusser discovered that a carefully-crafted RADIUS packet
could cause Ethereal to crash. It was also found that a zero-length
Presentation protocol selector could make Ethereal crash. Finally, a
corrupt color filter file could cause a segmentation fault. It is
possible, through the exploitation of some of these vulnerabilities, to
cause Ethereal to crash or run arbitrary code by injecting a malicious,
malformed packet onto the wire, by convincing someone to read a
malformed packet trace file, or by creating a malformed color filter
file.
The updated packages bring Ethereal to version 0.10.3 which is not
vulnerable to these issues.
