Hi, We are using CentOS 5.5 as a base OS for one of our products.The version of Glibc we are using was glibc-2.5-123.el5_11.1. We wanted to see whether this glibc is vulerable to CVE-2015-1781. I have gone through re-documentation & came across the following link https://access.redhat.com/security/cve/cve-2015-1781 In the link it is mentioned that, the CVE will not be fixed in Red-Hat 5 version. What does that mean? I mean, whether the RedHat 5 is vulnerable & fix is not available or RedHat 5 is not vulnerable, hence the fix is not given? Thanks for the info. -- Thanks & Regards, Venkat
