Synopsis

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

Description

The remote SUSE Linux SLES11 / SLES_SAP11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14764-1 advisory.

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-0512: Fixed a possible out of bounds write due to a heap buffer overflow in
__hidinput_change_resolution_multipliers. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bsc#1187595)
- CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. (bsc#1187452)
- CVE-2020-36386: Fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (bsc#1187038)
- CVE-2020-24588: Fixed a bug that could allow an adversary to abuse devices that support receiving non- SSP A-MSDU frames to inject arbitrary network packets. (bsc#1185861 bsc#1185863)
- CVE-2021-29154: Fixed an incorrect computation of branch displacements in the BPF JIT compilers, which could allow to execute arbitrary code within the kernel context. (bsc#1184391)
- CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c for removal of the HCI controller.
(bsc#1184611)
- CVE-2020-24586: Fixed a bug that, under the right circumstances, allows to inject arbitrary network packets and/or exfiltrate user data when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP. (bsc#1185859 bsc#1185863)
- CVE-2020-26139: Fixed a bug that allows an Access Point (AP) to forward EAPOL frames to other clients even though the sender has not yet successfully authenticated. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and made it easier to exploit other vulnerabilities in connected clients. (bsc#1185863 bsc#1186062)
- CVE-2020-24587: Fixed a bug that allows an adversary to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (bsc#1185862 bsc#1185863)

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.
