According to its self-reported version number, the remote Juniper Junos device is affected by an integer signedness error in the included GD Graphics Library (libgd) when handling compressed GD2 data due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via specially crafted compressed GD2 data, to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
