Lael Cellier discovered that Git incorrectly handled path strings in crafted Git repositories. A remote attacker could use this issue to cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking Git. (CVE-2016-2315, CVE-2016-2324).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
