Ubuntu Security Notice USN-3212-3
July 19, 2017
tiff vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 12.04 ESM
Summary:
LibTIFF could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
– tiff: Tag Image File Format (TIFF) library
Details:
USN-3212-1 and USN-3212-2 fixed a vulnerabilitiy in LibTIFF. This
update provides a subset of corresponding update for Ubuntu 12.04 ESM.
Original advisory details:
It was discovered that LibTIFF incorrectly handled certain malformed
images. If a user or automated system were tricked into opening a
specially crafted image, a remote attacker could crash the
application, leading to a denial of service, or possibly execute
arbitrary code with user privileges.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 ESM:
libtiff-tools 3.9.5-2ubuntu1.10
libtiff4 3.9.5-2ubuntu1.10
In general, a standard system update will make all the necessary
changes.
