		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">libtiff security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for libtiff is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">This libtiff provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.And contains command-line programs for manipulating TIFF format image files using the libtiff library.

Security Fix(es):

A heap buffer overflow in ExtractImageSection function in tiffcrop.c in libtiff library Version 4.3.0 allows attacker to trigger unsafe or out of bounds memory access via crafted TIFF image file which could result into application crash, potential information disclosure or any other context-dependent impact(CVE-2022-0891)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for libtiff is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.

openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
