Description: Researchers have identified a flaw in the WPA2 wireless encryption standard that could give attackers the ability to decrypt data. This flaw manifests as a key reinstallation vulnerability in the Wi-fi standard itself rather than any particular implementation. However, there are implementation-specific issues (such as the wpa_supplicant client used in Android and Linux) that could facilitate interception or manipulation of wireless traffic. Patches for this vulnerability in Android, Linux, Apple, and Windows are forthcoming or have already been developed and released.
Description: Oracle has released its quarterly set of security advisories to address various vulnerabilities that have been identified. This quarter's patch release addresses 252 vulnerabilities across Java, MySQL, Oracle Database, Fusion Middleware, and more. The Java update itself fixes 22 vulnerabilities with 20 of them potentially being remotely exploitable.
Description: Adobe has released an out-of-band security update for Flash Player in response to CVE-2017-11292, a zero-day vulnerability under active exploitation. CVE-2017-11292 manifests as a type confusion vulnerability. Reports have indicated that this vulnerability is being leveraged by the Black Oasis APT group. Users are advised to update as soon as possible to reduce the risk of compromise.
