USN-6229-1: LibTIFF vulnerabilities

It was discovered that LibTIFF was not properly handling variables used to
perform memory management operations when processing an image through
tiffcrop, which could lead to a heap buffer overflow. An attacker could
possibly use this issue to cause a denial of service or execute arbitrary
code. (CVE-2023-25433, CVE-2023-26965)

It was discovered that LibTIFF was not properly processing numerical
values when dealing with little-endian input data, which could lead to the
execution of an invalid operation. An attacker could possibly use this
issue to cause a denial of service (CVE-2023-26966)

It was discovered that LibTIFF was not properly performing bounds checks
when closing a previously opened TIFF file, which could lead to a NULL
pointer dereference. An attacker could possibly use this issue to cause a
denial of service. (CVE-2023-3316)
