Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2017-9693

Medium
5.5/10

Summary

The length of attribute value for STA_EXT_CAPABILITY in __wlan_hdd_change_station in Android for MSM, Firefox OS for MSM, and QRD Android before 2017-06-06 being less than the actual lenth of StaParams.extn_capability results in a read for extra bytes when a memcpy is done from params->ext_capab to StaParams.extn_capability using the sizeof(StaParams.extn_capability).

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.
