Synopsis

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

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0760-1 advisory.

- Amazon Linux has been made aware of a potential Branch Target Injection (BTI) issue (sometimes referred to as Spectre variant 2). This is a known cross-domain transient execution attack where a third party may seek to cause a disclosure gadget to be speculatively executed after an indirect branch prediction.
Generally, actors who attempt transient execution attacks do not have access to the data on the hosts they attempt to access (e.g. where privilege-level isolation is in place). For such attacks to succeed, actors need to be able to run code on the (virtual) machine hosting the data in which they are interested.
(CVE-2022-0001, CVE-2022-0002, CVE-2022-0847)

- A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
(CVE-2022-0492)

- kernel: missing check in ioctl allows kernel memory read/write (CVE-2022-0516)

- An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory. (CVE-2022-25375)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
