A flaw was found in apache-commons-compress. When reading a specially crafted 7Z archive, Compress can allocate large amounts of memory that leads to an out-of-memory error for very small inputs. This flaw allows the mounting of a denial of service attack against services that use Compress’ SevenZ package. The highest threat from this vulnerability is to system availability.
