Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 0.4% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A buffer overflow vulnerability exists in Microsoft Office 2003 SP3 and Office 2011 for Mac due to improper memory allocation when processing crafted PNG image data embedded in Office documents. The flaw, tracked as CWE-120 and also known as the Office Buffer Overflow Vulnerability, affects document handling components in these specific Office versions.

Remote attackers can exploit the issue by delivering a malicious Office document containing specially crafted PNG data. Successful exploitation grants the ability to execute arbitrary code on the target system with the privileges of the logged-in user, provided the document is opened.

Microsoft security bulletin MS13-051 and US-CERT alert TA13-168A address the vulnerability and direct administrators to apply the corresponding patches. OVAL definitions are available to support detection of affected installations.

No information on observed in-the-wild exploitation is supplied in the source data.

PR.PS-06 mostly match
prevents

Secure development practices directly enforce bounds checking and input validation that prevent classic buffer overflows.

ID.RA-01 partial match
prevents

Vulnerability identification processes such as code review or scanning detect classic buffer overflows before exploitation.

PR.PS-02 partial match
prevents

Routine patching replaces vulnerable code containing unchecked buffer copies with corrected versions.

prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

finds

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

prevents

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
