This update provides the corresponding update for Ubuntu 14.04 ESM. It was discovered that wpa_supplicant did not properly handle P2P group information in some situations, leading to a heap overflow. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that hostapd did not properly handle UPnP subscribe messages in some circumstances. An attacker could use this to cause a denial of service. Various other issues were also addressed.
