DESCRIPTION:
Francis Provencher has discovered multiple vulnerabilities in XnView,
which can be exploited by malicious people to compromise a user's
system.

1) A boundary error in the Xfpx.dll module when processing FlashPix
images can be exploited to cause a heap-based buffer overflow via a
specially crafted FPX file.

2) A boundary error in the NCSEcw.dll module when decompressing
Enhanced Compressed Wavelet images can be exploited to cause a
heap-based buffer overflow via a specially crafted ECW file.

3) An integer truncation error when processing Sun Raster images can
be exploited to cause a heap-based buffer overflow via a specially
crafted "Depth" value in a RAS file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code, but requires tricking a user into opening a malicious
image.

The vulnerabilities are confirmed in version 1.98.8. Other versions
may also be affected.

SOLUTION:
Update to version 1.99.
