Description Agostino Sarubbo gentoo-dev 2016-10-10 10:35:03 UTC
From ${URL} :

We recently reported two invalid memory accesses in the last revision
of libgit2:

* Read out-of-bounds in git_oid_nfmt:
https://github.com/libgit2/libgit2/issues/3936

* DoS using a null pointer derreference in git_commit_message:
https://github.com/libgit2/libgit2/issues/3937

The developers are preparing a patch to harden object parsing in libgit2 here:

https://github.com/libgit2/libgit2/pull/3956



@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
