Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2008-3247

Severity High
Score 7.2/10

Summary

The LDT implementation in the Linux kernel 2.6.25.x before 2.6.25.11 on x86_64 platforms uses an incorrect size for ldt_desc, which allows local users to cause a denial of service (system crash) or possibly gain privileges via unspecified vectors.

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.
