There is an edge-case during parsing that allows a bad actor to force the loop conditions to access arbitrary memory. Potentially, this could also leak memory if the extracted rev spec is reflected back to the attacker. As such, libgit2 versions before 1.4.0 are not affected. Users should upgrade to version 1.6.5 or 1.7.2.", "A flaw was found in libgit2, a cross-platform, linkable library implementation of Git. This flaw allows an attacker using a specially-crafted payload to `git_revparse_single` and cause the function to enter an infinite loop.
