| VAR-202104-2082 | No CVE | Command execution vulnerability exists in RG-EG Easy Gateway Management System |
CVSS V2: 7.1 CVSS V3: - Severity: HIGH |
RG-EG Easy Gateway Management System is a multi-service integrated gateway product launched by Ruijie Networks to solve the current network export problems.
There is a command execution vulnerability in the RG-EG Easy Gateway management system. Attackers can use this vulnerability to obtain root privileges of the device and execute arbitrary commands remotely.
| VAR-202104-0316 | CVE-2021-20453 | IBM WebSphere Application Server external entity injection vulnerability |
CVSS V2: 6.4 CVSS V3: 8.2 Severity: HIGH |
IBM WebSphere Application Server 8.0, 8.5, and 9.0 is vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 196648. This product is a platform for JavaEE and Web service applications, as well as the foundation of the IBM WebSphere software platform
| VAR-202104-1571 | CVE-2021-23133 | Linux kernel Competitive conditional vulnerability |
CVSS V2: 6.9 CVSS V3: 7.0 Severity: HIGH |
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. -----BEGIN PGP SIGNED MESSAGE-----

5. ==========================================================================
Ubuntu Security Notice USN-4997-2
June 25, 2021
linux-kvm vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-kvm: Linux kernel for cloud environments
Details:
USN-4997-1 fixed vulnerabilities in the Linux kernel for Ubuntu 21.04.
This update provides the corresponding updates for the Linux KVM
kernel for Ubuntu 21.04. A local attacker could use this issue to execute arbitrary
code. (CVE-2021-3609)
Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel
did not properly enforce limits for pointer operations. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2021-33200)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did
not properly clear received fragments from memory in some situations. A
physically proximate attacker could possibly use this issue to inject
packets or expose sensitive information. (CVE-2020-24586)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled encrypted fragments. A physically proximate attacker
could possibly use this issue to decrypt fragments. (CVE-2020-24587)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled certain malformed frames. If a user were tricked into
connecting to a malicious server, a physically proximate attacker could use
this issue to inject packets. (CVE-2020-24588)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
incorrectly handled EAPOL frames from unauthenticated senders. A physically
proximate attacker could inject malicious packets to cause a denial of
service (system crash). (CVE-2020-26139)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did
not properly verify certain fragmented frames. A physically proximate
attacker could possibly use this issue to inject or decrypt packets.
(CVE-2020-26141)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation
accepted plaintext fragments in certain situations. A physically proximate
attacker could use this issue to inject packets. (CVE-2020-26145)
Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation could
reassemble mixed encrypted and plaintext fragments. A physically proximate
attacker could possibly use this issue to inject packets or exfiltrate
selected fragments. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2021-23133)
Or Cohen and Nadav Markus discovered a use-after-free vulnerability in the
nfc implementation in the Linux kernel. A privileged local attacker could
use this issue to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2021-23134)
Manfred Paul discovered that the extended Berkeley Packet Filter (eBPF)
implementation in the Linux kernel contained an out-of-bounds
vulnerability. A local attacker could use this issue to execute arbitrary
code. (CVE-2021-31440)
Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel
did not properly prevent speculative loads in certain situations. A local
attacker could use this to expose sensitive information (kernel memory). An attacker could use this
issue to possibly execute arbitrary code. (CVE-2021-32399)
It was discovered that a use-after-free existed in the Bluetooth HCI driver
of the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2021-33034)
It was discovered that an out-of-bounds (OOB) memory access flaw existed in
the f2fs module of the Linux kernel. A local attacker could use this issue
to cause a denial of service (system crash). (CVE-2021-3506)
Mathias Krause discovered that a null pointer dereference existed in the
Nitro Enclaves kernel driver of the Linux kernel. A local attacker could
use this issue to cause a denial of service or possibly execute arbitrary
code. (CVE-2021-3543)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 21.04:
linux-image-5.11.0-1009-kvm 5.11.0-1009.9
linux-image-kvm 5.11.0.1009.9
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
