It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.

Cross Site Scripting (XSS) vulnerability in Teradek Sphere all firmware versions allows remote attackers to run arbitrary code via the Friendly Name field in System Information Settings. NOTE: Vedor states the product has reached End of Life and will not be receiving any firmware updates to address this issue.

There is a local privilege escalation vulnerability in some Huawei products. A local, authenticated attacker could craft specific commands to exploit this vulnerability. Successful exploitation may cause the attacker to obtain a higher privilege. Affected product versions include: ManageOne versions 6.5.0,6.5.0.SPC100.B210,6.5.1.1.B010,6.5.1.1.B020,6.5.1.1.B030,6.5.1.1.B040,6.5.1.SPC100.B050,6.5.1.SPC101.B010,6.5.1.SPC101.B040,6.5.1.SPC200,6.5.1.SPC200.B010,6.5.1.SPC200.B030,6.5.1.SPC200.B040,6.5.1.SPC200.B050,6.5.1.SPC200.B060,6.5.1.SPC200.B070,6.5.1RC1.B060,6.5.1RC2.B020,6.5.1RC2.B030,6.5.1RC2.B040,6.5.1RC2.B050,6.5.1RC2.B060,6.5.1RC2.B070,6.5.1RC2.B080,6.5.1RC2.B090,6.5.RC2.B050,8.0.0,8.0.0-LCND81,8.0.0.SPC100,8.0.1,8.0.RC2,8.0.RC3,8.0.RC3.B041,8.0.RC3.SPC100; NFV_FusionSphere versions 6.5.1.SPC23,8.0.0.SPC12; SMC2.0 versions V600R019C00,V600R019C10; iMaster MAE-M versions MAE-TOOL(FusionSphereBasicTemplate_Euler_X86)V100R020C10SPC220.

A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.

An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.

A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.

A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs. As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged execve() calls. This issue affects kernel versions before 4.8.

The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable.

Huawei FusionSphere OpenStack V100R006C00SPC102(NFV) has a privilege escalation vulnerability. Due to improper privilege restrictions, an attacker with high privilege may obtain the other users' certificates. Successful exploit may cause privilege escalation.
