SECURITY UPDATE: gpgv: Check for errors when splitting files (CVE-2016-1252)
This fixes a security issue where signatures of the InRelease files could be circumvented in a man-in-the-middle attack, giving attackers the ability to serve any packages they want to a system, in turn giving them root access. It turns out that getline() may not only return EINVAL as stated in the documentation - it might also return in case of an error when allocating memory. This fix not only adds a check that reading worked correctly, it also implicitly checks that all writes worked by reporting any other error that occurred inside the loop and was logged by apt. Affected: >= 0.9.8 Reported-By: Jann Horn <jannh@google.com> Thanks: Jann Horn, Google Project Zero for reporting the issue LP: #1647467 (cherry picked from commit 51be550c5c38a2e1ddfc2af50a9fab73ccf78026) (cherry picked from commit 4ef9e0837ce139b398299431ae2294882f531d8e)
