Package: release.debian.org Severity: normal Tags: jessie User: release.debian.org@packages.debian.org Usertags: pu Hello release team, CVE-2016-4021[1] hasn't been handled in jessie yet. The security team suggested to use an upcoming point release for this, this got ACKed by the stable security team. The pgpdump maintainer Jose Luis Rivas (CC'd) has agreed to this procedure. Find attached a debdiff based on the data in the tracker and upstream git, and can confirm the fix mitigates the issue. You might notice it's not the original patch, instead it includes a follow-up commit from upstream.[2] And while preparing the diff I realized it's probably a good idea to include commit 6e15953: "fixing a buffer overrun" that was found using the American fuzzy lop as well.
