The _dtoa_r function of the newlib libc library, prior to version 3.3.0, performs multiple memory allocations without checking their return value. This could result in NULL pointer dereference.

The REENT_CHECK macro (see newlib/libc/include/sys/reent.h) as used by REENT_CHECK_TM, REENT_CHECK_MISC, REENT_CHECK_MP and other newlib macros in versions prior to 3.3.0, does not check for memory allocation problems when the DEBUG flag is unset (as is the case in production firmware builds).

samba: samba AD DC LDAP denial of service via dirsync

A flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10. An attacker can crash AD DC LDAP server via dirsync resulting in denial of service. Privilege escalation is not possible with this issue.

Null pointer dereference in the FPGA kernel driver for Intel(R) Quartus(R) Prime Pro Edition before version 19.3 may allow an authenticated user to potentially enable denial of service via local access.

In libnasm.a in Netwide Assembler (NASM) 2.14.xx, asm/pragma.c allows a NULL pointer dereference in process_pragma, search_pragma_list, and nasm_set_limit when "%pragma limit" is mishandled.

An issue was discovered in Foxit PhantomPDF before 8.3.11. The application could crash when calling certain XFA JavaScript due to the use of, or access to, a NULL pointer without proper validation on the object.

An issue was discovered in Foxit PhantomPDF before 8.3.10. The application could be exposed to a NULL pointer dereference and crash when getting a PDF object from a document, or parsing a certain portfolio that contains a null dictionary.

In Bento4 1.5.1-627, AP4_DataBuffer::SetDataSize does not handle reallocation failures, leading to a memory copy into a NULL pointer. This is different from CVE-2018-20186.

sox: integer overflow in libsox.a leading to a NULL pointer dereference

An issue was discovered in libsox.a in SoX 14.4.2. In sox-fmt.h (startread function), there is an integer overflow on the result of integer addition (wraparound to 0) fed into the lsx_calloc macro that wraps malloc. When a NULL pointer is returned, it is used without a prior check that it is a valid pointer, leading to a NULL pointer dereference on lsx_readbuf in formats_i.c.

3S-Smart Software Solutions GmbH CODESYS V3 OPC UA Server, all versions 3.5.11.0 to 3.5.15.0, allows an attacker to send crafted requests from a trusted OPC UA client that cause a NULL pointer dereference, which may trigger a denial-of-service condition.

An issue was discovered in Bento4 1.5.1.0. A memory allocation failure is unhandled in Core/Ap4SdpAtom.cpp and leads to crashes. When parsing input video, the program allocates a new buffer to parse an atom in the stream. The unhandled memory allocation failure causes a direct copy to a NULL pointer.
