Multiple boundary checking vulnerabilities in libTIFF may allow for the remote execution of arbitrary code.
|Package||media-libs/tiff on all architectures|
|Affected versions||< 3.8.2-r8|
|Unaffected versions||>= 3.8.2-r8|
libTIFF provides support for reading and manipulating TIFF (Tagged Image File Format) images.
Two vulnerabilities have been reported in libTIFF:
A remote attacker could entice a user to open a specially crafted TIFF file with an application making use of libTIFF or the tiff2rgba and rgb2ycbcr tools, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All libTIFF users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/tiff-3.8.2-r8"
