kernel: security issues in the OS descriptor handling section of composite_setup function (composite.c)

An issue was discovered in drivers/usb/gadget/composite.c in the Linux kernel before 5.16.10. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). Memory corruption might occur.

Foxit PDF Reader and Editor before 11.2.1 and PhantomPDF before 10.1.7 allow a NULL pointer dereference during PDF parsing because the pointer is used without proper validation.

GPAC 1.0.1 is affected by a NULL pointer dereference in gf_utf8_wcslen. (gf_utf8_wcslen is a renamed Unicode utf8_wcslen function.)

GPAC 1.0.1 is affected by a NULL pointer dereference in gf_dump_vrml_field.isra ().

A Null Pointer Dereference vulnerability exists in GPAC 1.1.0 via the xtra_box_write function in /box_code_base.c, which causes a Denial of Service. This vulnerability was fixed in commit 71f9871.

kernel: local privileges escalation in kernel/bpf/verifier.c

kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types.

libreswan: Malicious IKEv1 packet can cause libreswan to restart

Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKEv1 packet because pluto/ikev1.c wrongly expects that a state object exists. This is fixed in 4.6.

On BIG-IP version 16.1.x before 16.1.1, 15.1.x before 15.1.4, 14.1.x before 14.1.4.4, and all versions of 13.1.x, when a SIP ALG profile is configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On BIG-IP version 16.1.x before 16.1.2, when an HTTP profile is configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On BIG-IP version 16.1.x before 16.1.2, when any of the following configurations are configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate: HTTP redirect rule in an LTM policy, BIG-IP APM Access Profile, and Explicit HTTP Proxy in HTTP Profile. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On BIG-IP version 16.1.x before 16.1.2, when the 'Respond on Error' setting is enabled on the Request Logging profile and configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On BIG-IP version 16.x before 16.1.0, 15.1.x before 15.1.4.1, 14.1.x before 14.1.4.5, and all versions of 13.1.x, when a virtual server is configured with a DNS profile with the Rapid Response Mode setting enabled and is configured on a BIG-IP system, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On versions 16.1.x before 16.1.2 and 15.1.x before 15.1.4.1, when BIG-IP SSL Forward Proxy with TLS 1.3 is configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A null pointer dereference was addressed with improved validation. This issue is fixed in tvOS 15.4, iOS 15.4 and iPadOS 15.4, macOS Big Sur 11.6.5, Security Update 2022-003 Catalina, watchOS 8.5, macOS Monterey 12.3. An attacker in a privileged position may be able to perform a denial of service attack.

Null Pointer Dereference in multiple CODESYS products can lead to a DoS.

An authenticated remote attacker can cause a null pointer dereference in the CmpSettings component of the affected CODESYS products which leads to a crash.

CODESYS: Null Pointer Dereference in CODESYS PROFINET stack

Codesys Profinet in version V4.2.0.0 is prone to null pointer dereference that allows a denial of service (DoS) attack of an unauthenticated user via SNMP.

Junos OS: QFX5000 Series and MX Series: An l2alm crash leading to an FPC crash can be observed in VxLAN scenario

A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on QFX5000 Series and MX Series allows an unauthenticated adjacent attacker to cause a Denial of Service (DoS). On QFX5K Series and MX Series, when the PFE receives a specific VxLAN packet the Layer 2 Address Learning Manager (L2ALM) process will crash leading to an FPC reboot. Continued receipt of this specific packet will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on QFX5000 Series, MX Series: 20.3 versions prior to 20.3R3-S3; 20.4 versions prior to 20.4R3-S2; 21.2 versions prior to 21.2R2-S1. This issue does not affect Juniper Networks Junos OS: All versions prior to 20.3R1; 21.1 version 21.1R1 and later versions.

NVIDIA GPU Display Driver for Windows contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for private IOCTLs where a NULL pointer dereference in the kernel, created within user mode code, may lead to a denial of service in the form of a system crash.

ClamAV Truncated File Denial of Service Vulnerability Affecting Cisco Products: April 2022

On May 4, 2022, the following vulnerability in the ClamAV scanning library versions 0.103.5 and earlier and 0.104.2 and earlier was disclosed: A vulnerability in Clam AntiVirus (ClamAV) versions 0.103.4, 0.103.5, 0.104.1, and 0.104.2 could allow an authenticated, local attacker to cause a denial of service condition on an affected device. For a description of this vulnerability, see the ClamAV blog.

Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerability

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to inadequate input validation of incoming CAPWAP packets encapsulating multicast DNS (mDNS) queries. An attacker could exploit this vulnerability by connecting to a wireless network and sending a crafted mDNS query, which would flow through and be processed by the wireless controller. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition.
