Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2016-1628

Medium
6.3/10

Summary

pi.c in OpenJPEG, as used in PDFium in Google Chrome before 48.0.2564.109, does not validate a certain precision value, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via a crafted JPEG 2000 image in a PDF document, related to the opj_pi_next_rpcl, opj_pi_next_pcrl, and opj_pi_next_cprl functions.

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.
