Category:F5 Local Security Checks
Title:F5 BIG-IP - Linux kernel vulnerability CVE-2015-1805
Summary:The remote host is missing a security patch.
Description:Summary:
The remote host is missing a security patch.

Vulnerability Insight:
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.' (CVE-2015-1805)

Vulnerability Impact:
A local unprivileged user may use this flaw to crash the system, or potentially escalate their privileges on the system.

Solution:
See the referenced vendor advisory for a solution.

CVSS Score:
7.2

CVSS Vector:
