Detailsinfo

A vulnerability has been found in Google Android (Smartphone Operating System) (affected version not known) and classified as critical. Affected by this vulnerability is some unknown functionality of the component ASN.1 Decoder. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in lib/asn1_decoder.c in the Linux kernel before 4.6 allows local users to gain privileges via crafted ASN.1 data.

The weakness was presented 10/05/2016 by Philip Pettersson with Samsung as Android Security Bulletin - October 2016 as confirmed security bulletin (Website). The advisory is shared at source.android.com. This vulnerability is known as CVE-2016-0758 since 12/16/2015. The attack can be launched remotely.
