Synopsis
========
Multiple heap-based buffer overflows in CDF might result in the
execution of arbitrary code.
Background
==========
CDF is a library for the Common Data Format which is a self-describing
data format for the storage and manipulation of scalar and
multidimensional data. It is developed by the NASA.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sci-libs/cdf < 3.3.0 >= 3.3.0
Description
===========
Leon Juranic reported multiple heap-based buffer overflows for instance
in the ReadAEDRList64(), SearchForRecord_r_64(), LastRecord64(), and
CDFsel64() functions.
Impact
======
A remote attacker could entice a user to open a specially crafted CDF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution

All CDF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =sci-libs/cdf-3.3.0
