Name of the Vulnerable Software and Affected Versions
Red Hat Enterprise Linux kernel versions prior to 3.18.8
Ubuntu linux-image-3.16.0
Ubuntu linux-image-3.2.0
Description
The issue concerns multiple vulnerabilities in the Linux kernel, specifically affecting Red Hat Enterprise Linux and Ubuntu. These vulnerabilities can be exploited remotely, potentially leading to a disruption of confidentiality, integrity, and availability of protected information. The vulnerabilities can cause a denial of service, slab corruption, and panic, or possibly have unspecified other impacts. This is achieved by triggering an INIT collision that leads to improper handling of shared-key data in the
sctp assoc update function in net/sctp/associola.c.Recommendations
For Red Hat Enterprise Linux kernel versions prior to 3.18.8: Update to a version 3.18.8 or later.
For Ubuntu linux-image-3.16.0 and linux-image-3.2.0: Update to a newer version that includes the fix for this issue.
As a temporary workaround, consider restricting access to the vulnerable
sctp assoc update function until a patch is available.Exploit
