Moderate: libtiff security update (Amazon Linux 2)

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2022-34266: A flaw was found in libtiff-4.0.3-35.amzn2.0.1 as packaged on Amazon Linux 2. When processing a malicious TIFF file, an invalid range may be passed as an argument to the memset() function within TIFFFetchStripThing() in tif_dirread.c. This will cause TIFFFetchStripThing() to segfault. Actors can use this issue to potentially cause a Denial of Service condition. CVE-2022-0562: A flaw was found in libtiff where a NULL source pointer passed as an argument to the memcpy() function within the TIFFReadDirectory() in tif_dirread.c. This flaw allows an attacker to exploit this vulnerability via a crafted TIFF file, causing a crash and leading to a denial of service.
