Severity: Normal
Title: Common Data Format library: User-assisted execution of
arbitrary code
Date: May 13, 2008
Bugs: #220391
ID: 200805-14

Synopsis

A buffer overflow vulnerability has been discovered in the Common Data
Format library.

Background

The Common Data Format library is a scientific data management package
which allows programmers and application developers to manage and
manipulate scalar, vector, and multi-dimensional data arrays in a
platform independent fashion.

Affected packages

-------------------------------------------------------------------
 Package       /  Vulnerable  /                         Unaffected
-------------------------------------------------------------------

1 sci-libs/cdf < 3.2.1 >= 3.2.1

Description

Alfredo Ortega (Core Security Technologies) reported a boundary error
within the Read32s_64() function when processing CDF files.

Impact

A remote attacker could entice a user to open a specially crafted CDF
file, possibly resulting in the remote execution of arbitrary code with
the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Common Data Format library users should upgrade to the latest
version:

# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=sci-libs/cdf-3.2.1&quot;
