Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.22.16 (Operating System). It has been declared as critical. Affected by this vulnerability is the function inet_sk_rebuild_header of the component DCCP. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system.

The bug was discovered 02/27/2017. The weakness was released 07/27/2018 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is known as CVE-2017-2634 since 11/30/2016. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 97415 (Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20170224)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Scientific Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 157391 (Oracle Enterprise Linux Security Update for kernel (ELSA-2017-0323-1)).

Upgrading to version 2.6.22.17 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (97415) and SecurityFocus (BID 96529†). Entry connected to this vulnerability is available at VDB-97118. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
