A vulnerability in the Open Shortest Path First (OSPF) implementation in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to incorrect processing of certain OSPF packets. An attacker could exploit this vulnerability by sending a series of crafted OSPF packets to be processed by an affected device. A successful exploit could allow the attacker to continuously consume memory on an affected device and eventually cause it to reload, resulting in a denial of service (DoS) condition.

A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust memory resources on the affected device, leading to a denial of service (DoS) condition. The vulnerability is due to improper resource management for inbound SSL/TLS connections. An attacker could exploit this vulnerability by establishing multiple SSL/TLS connections with specific conditions to the affected device. A successful exploit could allow the attacker to exhaust the memory on the affected device, causing the device to stop accepting new SSL/TLS connections and resulting in a DoS condition for services on the device that process SSL/TLS traffic. Manual intervention is required to recover an affected device.

A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Firepower Threat Defense (FTD) Software when running on the Cisco Firepower 1000 Series platform could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to a communication error between internal functions. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message to an affected device. A successful exploit could allow the attacker to cause a buffer underrun, which leads to a crash. The crash causes the affected device to reload.

There are two denial of service vulnerabilities on some Huawei smartphones. An attacker may send specially crafted TD-SCDMA messages from a rogue base station to the affected devices. Due to insufficient input validation of two values when parsing the messages, successful exploit may cause device abnormal. This is 1 out of 2 vulnerabilities. Different than CVE-2020-5303. Affected products are: ALP-AL00B: earlier than 9.1.0.333(C00E333R2P1T8) ALP-L09: earlier than 9.1.0.300(C432E4R1P9T8) ALP-L29: earlier than 9.1.0.315(C636E5R1P13T8) BLA-L29C: earlier than 9.1.0.321(C636E4R1P14T8), earlier than 9.1.0.330(C432E6R1P12T8), earlier than 9.1.0.302(C635E4R1P13T8) Berkeley-AL20: earlier than 9.1.0.333(C00E333R2P1T8) Berkeley-L09: earlier than 9.1.0.350(C10E3R1P14T8), earlier than 9.1.0.351(C432E5R1P13T8), earlier than 9.1.0.350(C636E4R1P13T8) Charlotte-L09C: earlier than 9.1.0.311(C185E4R1P11T8), earlier than 9.1.0.345(C432E8R1P11T8) Charlotte-L29C: earlier than 9.1.0.325(C185E4R1P11T8), earl…

Huawei mobile phones Ever-L29B versions earlier than 10.0.0.180(C185E6R3P3), earlier than 10.0.0.180(C432E6R1P7), earlier than 10.0.0.180(C636E5R2P3); HUAWEI Mate 20 RS versions earlier than 10.0.0.175(C786E70R3P8); HUAWEI Mate 20 X versions earlier than 10.0.0.176(C00E70R2P8); and Honor Magic2 versions earlier than 10.0.0.175(C00E59R2P11) have an improper authorization vulnerability. Due to improper authorization of some function, attackers can bypass the authorization to perform some operations.

Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit internal resource allocation when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. This could lead to a denial of service condition due to lack of memory for devices that include a vulnerable version of the stack. The security vulnerability could be exploited by an attacker with network access to an affected device. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the device.

A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service.

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.

An attacker with network access to an affected product may cause a denial of service condition by breaking the real-time synchronization (IRT) of the affected installation.
