Google fixed multiple vulnerabilities in Android

Google has released a security update Android Security Bulletin - June 2016 , in which various vulnerabilities in Android components are fixed. Multiple critical LPE vulnerabilities have been fixed in Qualcomm drivers: Video, Sound, GPU, Wi-Fi. Vulnerabilities in Qualcomm components are marked as critical, because in case of successful operation an attacker can execute his code with high privileges in the context of the Android kernel. Another critical RCE vulnerability with identifier CVE-2016-2463 has been closed in the Mediaserver system component, which is responsible for processing multimedia files. The exploitation of the vulnerability is possible with the use of a specially formed multimedia file, which can be sent via MMS or posted on a web page.



Other multiple LPE vulnerabilities in the High-priority Mediaserver component can be used by attackers to enhance their rights in Android. A total of 12 such vulnerabilities in Mediaserver are subject to correction. In this case, the malicious application can get the Signature or SignatureOrSystem rights, which are granted only to legitimate and system Android applications.
