Description Jan Lieskovsky 2010-07-02 12:20:42 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2010-2597 to
the following vulnerability:

The TIFFVStripSize function in tif_strip.c in LibTIFF 3.9.0 and 3.9.2
makes incorrect calls to the TIFFGetField function, which allows
remote attackers to cause a denial of service (application crash) via
a crafted TIFF image, related to "downsampled OJPEG input" and
possibly related to a compiler optimization that triggers a
divide-by-zero error.

Comment 1 Jan Lieskovsky 2010-07-02 12:23:10 UTC
This issue did NOT affect the version of the libtiff package,
as shipped with Red Hat Enterprise Linux 3.

This issue affects the versions of the libtiff package,
as shipped with Red Hat Enterprise Linux 4 and 5.

--

This issue does NOT affect the current versions of libtiff
and mingw32-libtiff packages, as shipped with Fedora releases of
12 and 13 (this flaws has been already addressed in those).

Comment 4 Tom Lane 2010-07-02 13:52:56 UTC
Actually, it's not so much a compiler optimization risk as use of uninitialized variables.  If the values happen to be zero to start with, you get a divide-by-zero.

Comment 5 errata-xmlrpc 2010-07-08 15:34:56 UTC
This issue has been addressed in following products:

  Red Hat Enterprise Linux 4
  Red Hat Enterprise Linux 5
