A flaw was found in the way Netty’s CookieDecoder method validated cookie name and value characters. An attacker could use this flaw to bypass the httpOnly flag on sensitive cookies. Upstream patch: https://github.com/slandelle/netty/commit/800555417e77029dcf8a31d7de44f27b5a8f79b8 External References: https://www.playframework.com/security/vulnerability/CVE-2015-2156-HttpOnlyBypass http://engineering.linkedin.com/security/look-netty%E2%80%99s-recent-security-update-cve%C2%AD-2015%C2%AD-2156

Netty is not used in EAP, and layered products, for parsing HTTP cookie headers, and hence is not affected by this flaw. Use of Netty in a unsupported way, such as parsing HTTP cookie headers could cause you to be vulnerable to this flaw.
ModeShape does not use Netty in JDV.
Most of the products that include Netty use it for TCP connection management for HornetQ messaging. We don't use it for parsing HTTP headers, so we won't fix this issue. We will upgrade the Netty package in Fedora in an upcoming release.
