libgit2 is a portable C implementation of the Git core methods provided as
a linkable library with a solid API, allowing to build Git functionality
into your application. Using well-crafted inputs to git_index_add
can
cause heap corruption that could be leveraged for arbitrary code execution.
There is an issue in the has_dir_name
function in src/libgit2/index.c
,
which frees an entry that should not be freed. The freed entry is later
used and overwritten with potentially bad actor-controlled data leading to
controlled heap corruption. Depending on the application that uses libgit2,
this could lead to arbitrary code execution. This issue has been patched in
version 1.6.5 and 1.7.2.
