The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5919-1 advisory.
A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function kcm_tx_work of the file net/kcm/kcmsock.c of the component kcm. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. VDB-211018 is the identifier assigned to this vulnerability. (CVE-2022-3521)
A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)
A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs when a user connects to a malicious USB device. This can allow a local user to crash the system or escalate their privileges. (CVE-2022-3628)
A vulnerability, which was classified as critical, was found in Linux Kernel. Affected is the function l2cap_conn_del of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211944. (CVE-2022-3640)
A vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects the function nilfs_attach_log_writer of the file fs/nilfs2/segment.c of the component BPF. The manipulation leads to memory leak. The attack may be initiated remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-211961 was assigned to this vulnerability. (CVE-2022-3646)
A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_new_inode of the file fs/nilfs2/inode.c of the component BPF. The manipulation leads to use after free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
The identifier of this vulnerability is VDB-211992. (CVE-2022-3649)
Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock could occur in case of netpoll being active for the interface the xen-netback driver is connected to (CVE-2022-42329). (CVE-2022-42328, CVE-2022-42329)
There is an infoleak vulnerability in the Linux kernel’s net/bluetooth/l2cap_core.c’s l2cap_parse_conf_req function which can be used to leak kernel pointers remotely. We recommend upgrading past commit https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e https://www.google.com/url (CVE-2022-42895)
drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user- space client to corrupt the monitor’s internal memory. (CVE-2022-43750)
A stack overflow flaw was found in the Linux kernel’s SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4378)
There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
