CVE-2020-18768 [MEDIUM] CWE-122 libtiff: heap-based buffer overflow in _TIFFmemcpy() in tif_unix.c
libtiff: heap-based buffer overflow in _TIFFmemcpy() in tif_unix.c
There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an attacker to cause a denial-of-service through a crafted tiff file.
A heap-based buffer overflow exists in libtiff in TIFFmemcpy. This flaw allows an attacker to craft a specific TIFF file, possibly causing a denial of service that results in a loss of the system’s availability.
Statement: Red Hat has determined that this vulnerability is of low impact as successful exploitation relies on convincing a user to manually open a malicious file with `tiffcp` and bypassing security mechanisms such ASLR.
