Fedora 27: libgit2 Security Update 2018-ca483ae3e0
Summary
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.
