Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9365 advisory.

 - Improper input validation in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4 and before version 1.4.29.0 for Windows*, may allow an authenticated user to potentially enable a denial of service via local access. (CVE-2020-24502)

 - Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4 may allow an authenticated user to potentially enable information disclosure via local access.
 (CVE-2020-24503)

 - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
 This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015) (CVE-2022-1016)

 - pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.
 (CVE-2021-45095)

 - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

 - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. (CVE-2022-27666)

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

Solution

Update the affected packages.
