F5 Networks BIG-IP : Linux kernel vulnerability (SOL17543)

medium Nessus Plugin ID 86729

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL17543.
