Vulnerability Data

IBM Db2 for Linux 12.1.0, 12.1.1, and 12.1.2 is vulnerable to a stack-based buffer overflow in db2fm, caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly counters the improper bounds checking on untrusted input that enables the stack buffer overflow in db2fm.

prevent

Provides memory-protection mechanisms (e.g., ASLR, stack canaries, NX) that block exploitation of the CWE-121 stack overflow.

detect

Detects unauthorized code or integrity violations resulting from successful arbitrary-code execution via the buffer overflow.

PR.PS-06 mostly match
prevents

Secure-development practices directly prevent introduction of stack buffer overflows.

ID.RA-01 partial match
prevents

Vulnerability scanning can discover stack buffer overflows but does not prevent their introduction.

PR.PS-02 partial match
prevents

Patching eliminates known instances of the weakness after discovery.

detects

Security testing (fuzzing, static analysis) detects stack overflows before release.

prevents

Secure SDLC mandates buffer-safety practices that directly prevent stack overflows.

prevents

Application security requirements can specify buffer-size and input-validation rules.

prevents

Secure architecture principles include memory-safety and least-privilege stack usage.

prevents

Secure coding standards explicitly forbid unsafe buffer handling that causes CWE-121.

none

Change-management gates can enforce security reviews that catch buffer issues.
