Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0362-1 advisory.

The SUSE Linux Enterprise 12 SP3 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-25020: Fixed an overflow in the BPF subsystem due to a mishandling of a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions. This affects kernel/bpf/core.c and net/core/filter.c (bnc#1193575).
- CVE-2019-0136: Fixed insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver that may have allowed an unauthenticated user to potentially enable denial of service via adjacent access (bnc#1193157).
- CVE-2020-35519: Fixed out-of-bounds memory access in x25_bind in net/x25/af_x25.c. A bounds check failure allowed a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information (bnc#1183696).
- CVE-2021-0935: Fixed possible out of bounds write in ip6_xmit of ip6_output.c due to a use after free.
This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1192032).
- CVE-2021-28711: Fixed issue with xen/blkfront to harden blkfront against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28712: Fixed issue with xen/netfront to harden netfront against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28713: Fixed issue with xen/console to harden hvc_xen against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28715: Fixed issue with xen/netback to do not queue unlimited number of packages (XSA-392) (bsc#1193442).
- CVE-2021-33098: Fixed improper input validation in the Intel(R) Ethernet ixgbe driver that may have allowed an authenticated user to potentially cause denial of service via local access (bnc#1192877).
- CVE-2021-3564: Fixed double-free memory corruption in the Linux kernel HCI device initialization subsystem that could have been used by attaching malicious HCI TTY Bluetooth devices. A local user could use this flaw to crash the system (bnc#1186207).
- CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a race condition in gadget_dev_desc_UDC_show of configfs.c. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation (bnc#1193861).
- CVE-2021-39657: Fixed out of bounds read due to a missing bounds check in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local information disclosure with System execution privileges needed (bnc#1193864).
- CVE-2021-4002: Fixed incorrect TLBs flush in hugetlbfs after huge_pmd_unshare (bsc#1192946).
- CVE-2021-4083: Fixed a read-after-free memory flaw inside the garbage collection for Unix domain socket file handlers when users call close() and fget() simultaneouslyand can potentially trigger a race condition (bnc#1193727).
- CVE-2021-4149: Fixed btrfs unlock newly allocated extent buffer after error (bsc#1194001).
- CVE-2021-4155: Fixed XFS map issue when unwritten blocks in XFS_IOC_{ALLOC,FREE}SP just like fallocate (bsc#1194272).
- CVE-2021-4197: Use cgroup open-time credentials for process migraton perm checks (bsc#1194302).
- CVE-2021-4202: Fixed NFC race condition by adding NCI_UNREG flag (bsc#1194529).
- CVE-2021-43976: Fixed insufficient access control in drivers/net/wireless/marvell/mwifiex/usb.c that allowed an attacker who connect a crafted USB device to cause denial of service (bnc#1192847).
- CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c (bnc#1193867).
- CVE-2021-45485: Fixed information leak in the IPv6 implementation in net/ipv6/output_core.c (bnc#1194094).
- CVE-2021-45486: Fixed information leak inside the IPv4 implementation caused by very small hash table (bnc#1194087).
- CVE-2022-0330: Fixed flush TLBs before releasing backing store (bsc#1194880).

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
