Description Arun Babu Neelicattu 2014-06-11 04:41:35 EDT

It was discovered that when handling specifically crafted SSL packets, the SslHandler implementation in Netty entered an infinite loop. An unauthenticated remote attacker could use this flaw to trigger a denial of service by CPU exhaustion.

Affects: 3.9.0, 3.9.1

Comment 1 Arun Babu Neelicattu 2014-06-11 04:46:29 EDT

Statement:

Netty versions as shipped by Red Hat products are not affected by this flaw.
