Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. The following security bug was fixed :

- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and AVX registers) between processes.
These registers might contain encryption keys when doing SSE accelerated AES enc/decryption (bsc#1087086)

The update package also includes non-security fixes. See advisory for details.

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