Synopsis

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

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3683-1 advisory.

The SUSE Linux Enterprise 15 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2023-37453: Fixed oversight in SuperSpeed initialization (bsc#1213123).
- CVE-2023-4569: Fixed information leak in nft_set_catchall_flush in net/netfilter/nf_tables_api.c (bsc#1214729).
- CVE-2023-4134: Fixed use-after-free in cyttsp4_watchdog_work() (bsc#1213971).
- CVE-2023-20588: Fixed a division-by-zero error on some AMD processors that can potentially return speculative data resulting in loss of confidentiality (bsc#1213927).
- CVE-2023-4459: Fixed a NULL pointer dereference flaw in vmxnet3_rq_cleanup that may have allowed a local attacker with normal user privilege to cause a denial of service (bsc#1214451).
- CVE-2023-3863: Fixed a use-after-free flaw was found in nfc_llcp_find_local that allowed a local user with special privileges to impact a kernel information leak issue (bsc#1213601).
- CVE-2023-3772: Fixed a flaw in XFRM subsystem that may have allowed a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer leading to a possible kernel crash and denial of service (bsc#1213666).
- CVE-2023-2007: Fixed a flaw in the DPT I2O Controller driver that could allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel (bsc#1210448).
- CVE-2023-4387: Fixed use-after-free flaw in vmxnet3_rq_alloc_rx_buf that could allow a local attacker to crash the system due to a double-free (bsc#1214350).
- CVE-2023-3610: Fixed use-after-free vulnerability in nf_tables can be exploited to achieve local privilege escalation (bsc#1213580).
- CVE-2023-4128: Fixed a use-after-free flaw in net/sched/cls_fw.c that allowed a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue (bsc#1214149).
- CVE-2023-4273: Fixed a flaw in the exFAT driver of the Linux kernel that alloawed a local privileged attacker to overflow the kernel stack (bsc#1214120).
- CVE-2023-4147: Fixed use-after-free in nf_tables_newrule (bsc#1213968).
- CVE-2023-4133: Fixed use after free bugs caused by circular dependency problem in cxgb4 (bsc#1213970).
- CVE-2023-34319: Fixed buffer overrun triggered by unusual packet in xen/netback (XSA-432) (bsc#1213546).
- CVE-2023-4194: Fixed a type confusion in net tun_chr_open() (bsc#1214019).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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.
