Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2018-0429

Severity High
Score 7.8/10

Summary

Stack-based buffer overflow in the Cisco Thor decoder before commit 18de8f9f0762c3a542b1122589edb8af859d9813 allows local users to cause a denial of service (segmentation fault) and execute arbitrary code via a crafted non-conformant Thor bitstream.

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.
