An update that solves 20 vulnerabilities and has 10 fixes
is now available.
Description:
The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2021-22555: Fixed an heap out-of-bounds write in
net/netfilter/x_tables.c that could allow local provilege escalation.
(bsc#1188116)
- CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer
that allows to obtain full root privileges. (bsc#1188062)
- CVE-2021-3609: Fixed a race condition in the CAN BCM networking protocol
which allows for local privilege escalation. (bsc#1187215)
- CVE-2021-0605: Fixed an out-of-bounds read which could lead to local
information disclosure in the kernel with System execution privileges
needed. (bsc#1187601)
- CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to
local escalation of privilege with no additional execution privileges
needed. (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-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for
local privilege escalation. (bsc#1187050)
- CVE-2021-0129: Fixed an improper access control in BlueZ that may have
allowed an authenticated user to potentially enable information
disclosure via adjacent access. (bsc#1186463)
- CVE-2020-26558: Fixed a flaw in the Bluetooth LE and BR/EDR secure
pairing that could permit a nearby man-in-the-middle attacker to
identify the Passkey used during pairing. (bsc#1179610)
- 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)
- CVE-2021-32399: Fixed a race condition in net/bluetooth/hci_request.c
for removal of the HCI controller. (bsc#1184611)
- CVE-2021-33034: Fixed an issue in net/bluetooth/hci_event.c where a
use-after-free leads to writing an arbitrary value. (bsc#1186111)
- 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#1186062)
- CVE-2021-23134: Fixed a use After Free vulnerability in nfc sockets
which allows local attackers to elevate their privileges. (bsc#1186060)
- 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)
- CVE-2020-26141: Fixed a flaw that could allows an adversary to inject
and possibly decrypt packets in WPA or WPA2 networks that support the
TKIP data-confidentiality protocol. (bsc#1185987)
- CVE-2020-26145: Fixed a bug in the WEP, WPA, WPA2, and WPA3
implementations that could allows an adversary to inject arbitrary
network packets. (bsc#1185860)
- 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)
- CVE-2020-26147: Fixed a bug in the WEP, WPA, WPA2, and WPA3
implementations that could allows an adversary to inject packets and/or
exfiltrate selected fragments when another device sends fragmented
frames. (bsc#1185987)
