Solaris 11 : Multiple Kernel Vulnerabilities

high Nessus Plugin ID 100997

Synopsis

The remote Solaris host is missing a vendor-supplied security patch.

Description

The remote Solaris host is missing a vendor-supplied security patch.
It is, therefore, affected by the following vulnerabilities :

- Multiple security bypass vulnerabilities exist in the Kernel subcomponent that allow a specially crafted application to circumvent the stack guard page security mechanism. A local attacker can exploit these, by using stack clash methods, to gain elevated privileges.
(CVE-2017-3629, CVE-2017-3630)

- A privilege escalation vulnerability exists in the Kernel subcomponent when UID binaries are invoked via a hard-link using a different pathname. A local attacker can exploit this to gain elevated privileges.
(CVE-2017-3631)

Solution

Install SRU 11.3.21.5.0 from the Oracle support website.
