Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2014-9777

High
7.8/10

Summary

The vid_dec_set_meta_buffers function in drivers/video/msm/vidc/common/dec/vdec.c in the Qualcomm components in Android before 2016-07-05 on Nexus 5 and 7 (2013) devices does not validate the number of buffers, which allows attackers to gain privileges via a crafted application, aka Android internal bug 28598501 and Qualcomm internal bug CR563654.

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.
