Fedora 27: FEDORA-2018-ca483ae3e0 Critical: Libgit2 Out-Of-Bounds Read

libgit2 is a portable, pure C implementation of the Git core methods

provided as a re-entrant linkable library with a solid API, allowing

you to write native speed custom Git applications in any language

with bindings.

This is a security release fixing out-of-bounds reads when processing smart-protocol "ng" packets. When parsing an "ng" packet, we keep track of both the

current position as well as the remaining length of the packet itself. But

instead of taking care not to exceed the length, we pass the current pointer's

position to strchr, which will search for a certain character until hitting NUL.

It is thus possible to create a crafted packet which doesn't contain a NUL byte

to trigger an out-of-bounds read. The issue was discovered by the oss-fuzz

project, issue 9406.
