1) Input validation error

EUVDB-ID: #VU33953

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2012-1173

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Multiple integer overflows in tiff_getimage.c in LibTIFF 3.9.4 allow remote attackers to execute arbitrary code via a crafted tile size in a TIFF file, which is not properly handled by the (1) gtTileSeparate or (2) gtStripSeparate function, leading to a heap-based buffer overflow.
