CVE-2022-34266: Input Validation
Amazon Linux is vulnerable to a denial of service, caused by improper input validation by the memset() function within TIFFFetchStripThing() in tifdirread.c. By persuading a victim to open a specially-crafted TIFF file, a remote attacker could exploit this vulnerability to cause the application to crash.
Other sources
The libtiff-4.0.3-35.amzn2.0.1 package for LibTIFF on Amazon Linux 2 allows attackers to cause a denial of service (application crash), a different vulnerability than CVE-2022-0562. When processing a malicious TIFF file, an invalid range may be passed as an argument to the memset() function within TIFFFetchStripThing() in tifdirread.c. This will cause TIFFFetchStripThing() to segfault after use of an uninitialized resource.
