Summary

CVE-2009-3459 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Adobe Acrobat. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.3% 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 heap-based buffer overflow vulnerability, also referenced under CWE-119 and CWE-122, affects Adobe Reader and Acrobat versions 7.x prior to 7.1.4, 8.x prior to 8.1.7, and 9.x prior to 9.2. The flaw resides in PDF processing code and can trigger memory corruption when a specially crafted document is handled.

Remote attackers can exploit the issue by supplying a malicious PDF file, enabling arbitrary code execution on the target system. The vulnerability carries a CVSS score of 8.8 and was observed being exploited in the wild during October 2009.

Adobe security bulletins APSB09-15 and the associated PSIRT advisory, along with vendor updates from Secunia and SecurityTracker, direct users to apply the fixed releases to address the exposure. The issue was publicly disclosed with confirmation of active exploitation at the time of release.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-119

Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.

addresses: CWE-119

Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.

addresses: CWE-119

Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.

addresses: CWE-119

Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-119, a class-level weakness. Rules are authored against its narrower children: CWE-823.
