Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2014-9655

Severity Medium
Score 6.5/10

Summary

The (1) putcontig8bitYCbCr21tile function in tif_getimage.c or (2) NeXTDecode function in tif_next.c in LibTIFF before 4.0.4 allows remote attackers to cause a denial of service (uninitialized memory access) via a crafted TIFF image, as demonstrated by libtiff-cvs-1.tif and libtiff-cvs-2.tif.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
