F5 Networks BIG-IP : Linux kernel vulnerability (SOL17458)

High Nessus Plugin ID 86449

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.9

Synopsis

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

Description

The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an 'I/O vector array overrun.'

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL17458.
