Ubuntu 15.10 : linux-raspi2 vulnerability (USN-2978-3)

high Nessus Plugin ID 91187

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Philip Pettersson discovered that the Linux kernel's ASN.1 DER decoder did not properly process certificate files with tags of indefinite length. A local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected linux-image-4.2-raspi2 package.
