Issue Overview:

An integer truncation flaw (CVE-2016-2315) and an integer overflow flaw (CVE-2016-2324), both leading to a heap-based buffer overflow, were found in the way Git processed certain path information. A remote attacker could create a specially crafted Git repository that would cause a Git client or server to crash or, possibly, execute arbitrary code.
