It seems like commit a817832c223 (szukw000:AFL\_PATCH\_0) was the final
commit created by a contributor in order to fix this issue. This
commit contains the changes in commit 7b28bd2b723 (szukw000:863-862)
which originally attempts to fix this issue. Commit a817832c223 (pull
request 895 for more information) contains the changes in commit

however, was never merged and issue 892, related to this CVE, was
instead fixed by another commit: 2fa0fc61f2d (which seems to have
introduced a regression, fixed by 784d4d47e97).
