Detailsinfo

A vulnerability, which was classified as critical, was found in Google Android (Smartphone Operating System) (affected version not known). This affects some unknown functionality of the component Kernel Netfilter Subsystem. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The netfilter subsystem in the Linux kernel through 4.5.2 does not validate certain offset fields, which allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.

The weakness was presented 09/06/2016 as Android Security Bulletin - September 2016 as confirmed security bulletin (Website). It is possible to read the advisory at source.android.com. This vulnerability is uniquely identified as CVE-2016-3134 since 03/13/2016. Attacking locally is a requirement. A authentication is required for exploitation. Technical details are unknown but a public exploit is available.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 93278 (SUSE SLES12 Security Update : kernel (SUSE-SU-2016:2006-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 157314 (Oracle Enterprise Linux Security Update for kernel (ELSA-2016-2574)-Deprecated).

Upgrading eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (39545), Tenable (93278) and SecurityFocus (BID 84305†). See VDB-81386, VDB-82951, VDB-82953 and VDB-82963 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
