Description Aleksandr Wagner (Kivak) 2017-10-15 14:55:39 UTC
CVE-2017-15298 (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-15298):

Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.
