Details

USN-1085-1 fixed vulnerabilities in the system TIFF library. The upstream
fixes were incomplete and created problems for certain CCITTFAX4 files.
This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Sauli Pahlman discovered that the TIFF library incorrectly handled invalid
td_stripbytecount fields. If a user or automated system were tricked into
opening a specially crafted TIFF image, a remote attacker could crash the
application, leading to a denial of service. This issue only affected
Ubuntu 10.04 LTS and 10.10. (CVE-2010-2482)

Sauli Pahlman discovered that the TIFF library incorrectly handled TIFF
files with an invalid combination of SamplesPerPixel and Photometric
values. If a user or automated system were tricked into opening a specially
crafted TIFF image, a remote attacker could crash the application, leading
to a denial of service. This issue only affected Ubuntu 10.10.
(CVE-2010-2482)

Nicolae Ghimbovschi discovered that the TIFF library incorrectly handled
invalid ReferenceBlackWhite values. If a user or automated system were
tricked into opening a specially crafted TIFF image, a remote attacker
could crash the application, leading to a denial of service.
(CVE-2010-2595)

Sauli Pahlman discovered that the TIFF library incorrectly handled certain
default fields. If a user or automated system were tricked into opening a
specially crafted TIFF image, a remote attacker could crash the
application, leading to a denial of service. (CVE-2010-2597, CVE-2010-2598)

It was discovered that the TIFF library incorrectly validated certain
data types. If a user or automated system were tricked into opening a
specially crafted TIFF image, a remote attacker could crash the
application, leading to a denial of service. (CVE-2010-2630)

It was discovered that the TIFF library incorrectly handled downsampled
JPEG data. If a user or automated system were tricked into opening a
specially crafted TIFF image, a remote attacker could execute arbitrary
code with user privileges, or crash the application, leading to a denial of
service. This issue only affected Ubuntu 10.04 LTS and 10.10.
(CVE-2010-3087)

It was discovered that the TIFF library incorrectly handled certain JPEG
data. If a user or automated system were tricked into opening a specially
crafted TIFF image, a remote attacker could execute arbitrary code with
user privileges, or crash the application, leading to a denial of service.
This issue only affected Ubuntu 6.06 LTS, 8.04 LTS and 9.10.
(CVE-2011-0191)

It was discovered that the TIFF library incorrectly handled certain TIFF
FAX images. If a user or automated system were tricked into opening a
specially crafted TIFF FAX image, a remote attacker could execute arbitrary
code with user privileges, or crash the application, leading to a denial of
service. (CVE-2011-0191)
