libTIFF: Multiple buffer overflows — GLSA 200607-03

libTIFF contains buffer overflows that could result in arbitrary code execution.

Affected Packages

media-libs/tiff on all architectures
Affected versions < 3.8.2-r1
Unaffected versions >= 3.8.2-r1

Background

libTIFF provides support for reading and manipulating TIFF images.

Description

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.

Impact

A remote attacker could entice a user to load a specially crafted TIFF file, resulting in the possible execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All libTIFF users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r1"
