Synopsis

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

Description

The remote SUSE Linux SLED12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3748-1 advisory.

The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-3655: Fixed a missing size validations on inbound SCTP packets, which may have allowed the kernel to read uninitialized memory (bsc#1188563).
- CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/cls_route.c (bsc#1190349).
- CVE-2021-33033: Fixed a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled (bsc#1186109).
- CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).
- CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv- avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).
- CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).
- CVE-2021-34556: Fixed side-channel attack via a Speculative Store Bypass via unprivileged BPF program that could have obtain sensitive information from kernel memory (bsc#1188983).
- CVE-2021-35477: Fixed BPF stack frame pointer which could have been abused to disclose content of arbitrary kernel memory (bsc#1188985).
- CVE-2021-42252: Fixed an issue inside aspeed_lpc_ctrl_mmap that could have allowed local attackers to access the Aspeed LPC control interface to overwrite memory in the kernel and potentially execute privileges (bnc#1190479).
- CVE-2021-41864: Fixed prealloc_elems_and_freelist that allowed unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
- CVE-2021-42008: Fixed a slab out-of-bounds write in the decode_data function in drivers/net/hamradio/6pack.c. Input from a process that had the CAP_NET_ADMIN capability could have lead to root access (bsc#1191315).
- CVE-2021-37159: Fixed use-after-free and a double free inside hso_free_net_device in drivers/net/usb/hso.c when unregister_netdev is called without checking for the NETREG_REGISTERED state (bnc#1188601).

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.
