FreeBSD : cdf3 -- Buffer overflow vulnerability (c4f31e16-6e33-11dd-8eb7-0011098ad87f)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

NASA Goddard Space Flight Center reports :

The libraries for the scientific data file format, Common Data Format
(CDF) version 3.2 and earlier, have the potential for a buffer
overflow vulnerability when reading specially crafted (invalid) CDF
files. If successful, this could trigger execution of arbitrary code
within the context of the CDF-reading program that could be exploited
to compromise a system, or otherwise crash the program. While it's
unlikely that you would open CDFs from untrusted sources, we recommend
everyone upgrade to the latest CDF libraries on their systems,
including the IDL and Matlab plugins. Most worrisome is any service
that enables the general public to submit CDF files for processing.

The vulnerability is in the CDF library routines not properly checking
the length tags on a CDF file before copying data to a stack buffer.
Exploitation requires the user to explicitly open a specially crafted
file. CDF users should not open files from untrusted third parties
until the patch is applied (and continue then to exercise normal
caution for files from untrusted third parties).
