[Yaakov (Cygwin/X)]

Chuck,

Security vulnerabilities have been announced in the tiff package.  The
remedy is to update to the latest 3.9.4 release AND apply the following
patches:

http://pkgs.fedoraproject.org/gitweb/?p=libtiff.git;a=blob_plain;f=libtiff-CVE-2011-0192.patch
http://pkgs.fedoraproject.org/gitweb/?p=libtiff.git;a=blob_plain;f=libtiff-CVE-2011-1167.patch

This has been hanging for two months already, so I went ahead and added
this to Cygwin Ports CVS[1], in module ports/libs/tiff.  I hope our
maintainer (Charles?) will be able to roll this out ASAP.

And now, there's more:

A buffer overflow has been found in the t2p_write_pdf_string function in
tiff2pdf, which can been triggered with a TIFF file containing a
DocumentName tag with UTF-8 characters. An additional buffer overflow
has been found in the handling of the parameters in tiffsplit.

Solution: update to 3.8.2 and apply the following patches:
http://www.gentoo.org/cgi-bin/viewcvs.cgi/*checkout*/media-libs/tiff/files/tiff-3.8.2-tiffsplit.patch
http://www.gentoo.org/cgi-bin/viewcvs.cgi/*checkout*/media-libs/tiff/files/tiff-buffer.patch
