CVE-2010-4476
CVE-2010-4476 is a security vulnerability in sun jdk. 1 public exploit reference exists, so weaponization risk is real. O3 Security detects and blocks CVE-2010-4476 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
The Double.parseDouble method in Java Runtime Environment (JRE) in Oracle Java SE and Java for Business 6 Update 23 and earlier, 5.0 Update 27 and earlier, and 1.4.2_29 and earlier, as used in OpenJDK, Apache, JBossweb, and other products, allows remote attackers to cause a denial of service via a crafted string that triggers an infinite loop of estimations during conversion to a double-precision binary floating-point number, as demonstrated using 2.2250738585072012e-308.

Detection & mitigation playbook
Vendor / applianceDetect
Inventory every sun jdk 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 exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2010-4476 yet — track the sun jdk advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
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 O3 protects you
O3 detects and blocks CVE-2010-4476 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2010-4476. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2010-4476 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2010-4476 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
