Description
==========
- CVE-2022-0561 (denial of service)

Null source pointer passed as an argument to memcpy() function within
TIFFFetchStripThing() in tif_dirread.c in libtiff versions from 3.9.0
to 4.3.0 could lead to Denial of Service via crafted TIFF file.

- CVE-2022-0562 (denial of service)

Null source pointer passed as an argument to memcpy() function within
TIFFReadDirectory() in tif_dirread.c in libtiff versions from 4.0 to
4.3.0 could lead to Denial of Service via crafted TIFF file.

- CVE-2022-0865 (denial of service)

Reachable Assertion in tiffcp in libtiff 4.3.0 allows attackers to
cause a denial-of-service via a crafted tiff file.

- CVE-2022-0891 (arbitrary code execution)

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-2022-0907 (denial of service)

Unchecked Return Value to NULL Pointer Dereference in tiffcrop in
libtiff 4.3.0 allows attackers to cause a denial-of-service via a
crafted tiff file.

- CVE-2022-0908 (denial of service)

Null source pointer passed as an argument to memcpy() function within
TIFFFetchNormalTag () in tif_dirread.c in libtiff versions up to 4.3.0
could lead to Denial of Service via crafted TIFF file.

- CVE-2022-0909 (denial of service)

A division by zero error in tiffcrop in libtiff 4.3.0 allows attackers
to cause a denial-of-service via a crafted tiff file.

- CVE-2022-0924 (denial of service)

Out-of-bounds Read error in tiffcp in libtiff 4.3.0 allows attackers to
cause a denial-of-service via a crafted tiff file.

- CVE-2022-22844 (denial of service)

LibTIFF 4.3.0 has an out-of-bounds read in _TIFFmemcpy in tif_unix.c in
certain situations involving a custom tag and 0x0200 as the second word
of the DE field.

Impact
=====
A remote attacker is able to crash the application or execute arbitrary
code on the affected host via a crafted tiff file.
