Which products are affected by CVE-2013-3346?

Affected package information for CVE-2013-3346 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2013-3346?

Apply the adobe acrobat security patch or hotfix for CVE-2013-3346 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2013-3346 across my infrastructure?

Inventory every adobe acrobat deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2013-3346 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2013-3346?

O3 detects and blocks CVE-2013-3346 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2013-3346 actively exploited in the wild?

Yes. There are 4 known exploit references for CVE-2013-3346, including 1 documented proof-of-concept exploit on Exploit-DB and 3 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2013-3346?

CVE-2013-3346 has an EPSS (Exploit Prediction Scoring System) score of 78.6%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2013-3346 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2013-3346 (Adobe Reader and Acrobat Memory Corruption Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-03-03. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-03-24. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2013-3346?

CVE-2013-3346 is classified as Out-of-bounds Write (CWE-787). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2013-3346?

CVE-2013-3346 affects adobe acrobat; adobe acrobat reader. Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2013-3346 published, and has it been updated?

CVE-2013-3346 was published on August 30, 2013 and was last updated on June 16, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
