The create_fullest_file_path function in libdwarf before 20160923 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted dwarf file.

In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.

A NULL pointer dereference is present in libyang before v1.0-r3 in the function lys_extension_instances_free() due to a copy of unresolved extensions in lys_restr_dup(). Applications that use libyang to parse untrusted input yang files may crash.

bitstr_tell at bitstr.c in ffjpeg through 2019-08-21 has a NULL pointer dereference related to jfif_encode.

An issue was discovered in ezXML 0.8.2 through 0.8.6. The function ezxml_str2utf8, while parsing a crafted XML file, performs zero-length reallocation in ezxml.c, leading to returning a NULL pointer (in some compilers). After this, the function ezxml_parse_str does not check whether the s variable is not NULL in ezxml.c, leading to a NULL pointer dereference and crash (segmentation fault).

Bento4 1.5.1.0 has a NULL pointer dereference in AP4_Descriptor::GetTag in Core/Ap4Descriptor.h, related to AP4_StsdAtom::GetSampleDescription in Core/Ap4StsdAtom.cpp, as demonstrated by mp4info.

Bento4 1.5.1.0 has a NULL pointer dereference in AP4_DescriptorListWriter::Action in Core/Ap4Descriptor.h, related to AP4_IodsAtom::WriteFields in Core/Ap4IodsAtom.cpp, as demonstrated by mp4encrypt or mp4compact.

libde265 v1.0.10 was discovered to contain a NULL pointer dereference in the mc_chroma function at motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted input file.

Bento4 1.5.1.0 has a NULL pointer dereference in AP4_DescriptorListInspector::Action in Core/Ap4Descriptor.h, related to AP4_IodsAtom::InspectFields in Core/Ap4IodsAtom.cpp, as demonstrated by mp4dump.

LibSass before 3.6.3 allows a NULL pointer dereference in Sass::Parser::parseCompoundSelector in parser_selectors.cpp.

marc-q libwav through 2017-04-20 has a NULL pointer dereference in gain_file() at wav_gain.c.

ffjpeg before 2019-08-18 has a NULL pointer dereference in idct2d8x8() at dct.c.

An issue was discovered in libezxml.a in ezXML 0.8.6. The function ezxml_internal_dtd(), while parsing a crafted XML file, performs incorrect memory handling, leading to a NULL pointer dereference while running strcmp() on a NULL pointer.

The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.

An issue was discovered in Binaryen 1.38.32. Two visitors in ir/ExpressionManipulator.cpp can lead to a NULL pointer dereference in wasm::LocalSet::finalize in wasm/wasm.cpp. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm2js.

OTFCC v0.10.4 was discovered to contain a segmentation violation via /release-x64/otfccdump+0x6b6a8f.

WebKit in Google Chrome before Blink M11 and M12 does not properly handle counter nodes, which allows remote attackers to cause a denial of service (memory corruption).

A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma 6.9.2 allows attackers to potentially cause denial of service by providing a crafted regular expression. Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.

In Audio File Library (aka audiofile) 0.3.6, there exists one NULL pointer dereference bug in ulaw2linear_buf in G711.cpp in libmodules.a that allows an attacker to cause a denial of service via a crafted file.

Libde265 v1.0.11 was discovered to contain a segmentation violation via the function decoder_context::process_slice_segment_header at decctx.cc.

A NULL pointer dereference was discovered in wasm::WasmBinaryBuilder::processFunctions() in wasm/wasm-binary.cpp (when calling wasm::WasmBinaryBuilder::getFunctionIndexName) in Binaryen 1.38.22. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm-opt.

lunasvg v3.0.0 was discovered to contain a segmentation violation via the component blend_transformed_tiled_argb.isra.0.

libmobi before v0.10 contains a NULL pointer dereference via the component mobi_buffer_getpointer. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted mobi file.

A null pointer deference issue exists in GNU LibreDWG 0.10 via get_bmp ../../programs/dwgbmp.c:164.

D-Link DIR-823G A1V1.0.2B05 was found to contain a Null-pointer dereference in the main function of upload_firmware.cgi, which allows remote attackers to cause a Denial of Service (DoS) via a crafted input.

Ming (aka libming) 0.4.8 has z NULL pointer dereference in the function decompileGETURL2() in decompile.c.

When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects Thunderbird < 68.5.
