Null pointer dereference vulnerability in the PDF preview module Impact: Successful exploitation of this vulnerability may affect function stability.

A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.

A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server may cause the libsoup client to crash.

A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.

A NULL pointer dereference was discovered in wasm::SExpressionWasmBuilder::parseExpression in wasm-s-parser.cpp in Binaryen 1.38.22. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm-as.

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.

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

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

An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_decode, while parsing a crafted XML file, performs incorrect memory handling, leading to NULL pointer dereference while running strlen() on a NULL pointer.

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).

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

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

A NULL Pointer Dereference vulnerability in DumpTS v0.1.0-nightly allows attackers to cause a denial of service via the function VerifyCommandLine() at /src/DumpTS.cpp.

An uninitialized pointer dereference in the ngap_handle_pdu_session_resource_setup_response routine of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a crafted PDU Session Resource Setup Response.

libjbig2dec.a in Artifex jbig2dec 0.13, as used in MuPDF and Ghostscript, has a NULL pointer dereference in the jbig2_huffman_get function in jbig2_huffman.c. For example, the jbig2dec utility will crash (segmentation fault) when parsing an invalid file.

NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. In version 0.24.6, NanoMQ has a protocol parsing / forwarding inconsistency when handling shared subscriptions ($share/). A malformed SUBSCRIBE topic such as $share/ab (missing the second /) is not strictly validated during the subscription stage, so the invalid Topic Filter is stored into the subscription table. Later, when any PUBLISH matches this subscription, the broker send path (nmq_pipe_send_start_v4/v5) performs a second $share/ parsing using strchr() and increments the returned pointer without NULL checks. If the second strchr() returns NULL, sub_topic++ turns the pointer into an invalid address (e.g. 0x1). This invalid pointer is then passed into topic_filtern(), which triggers strlen() and crashes with SIGSEGV. The crash is stable and remotely triggerable. This issue has been patched in version 0.24.7.

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

Null pointer dereference vulnerability in the PDF preview module Impact: Successful exploitation of this vulnerability may affect function stability.

A null pointer dereference may have inadvertently occurred in `pk12util`, and specifically in the `SEC_ASN1DecodeItem_Util` function, when handling malformed or improperly formatted input files. This vulnerability affects Firefox < 133 and Thunderbird < 133.

NULL pointer dereference vulnerability in FreeImage before 1.18.0 via the FreeImage_CloneTag function inFreeImageTag.cpp.

Null pointer dereference when viewing a specially crafted email in Mutt >1.5.2 <2.2.12

In SVGPP SVG++ library 1.3.0, the XMLDocument::getRoot function in the renderDocument function handled the XMLDocument object improperly, returning a null pointer in advance at the second if, resulting in a null pointer reference behind the renderDocument function.

Null Pointer Dereference in mask_cidr6 component at cidr.c in Tcpreplay 4.4.4 allows attackers to crash the application via crafted tcprewrite command.

An exploitable denial of service vulnerability exists in the web server functionality of Moxa EDR-810 V4.1 build 17030317. A specially crafted HTTP URI can cause a null pointer dereference resulting in the web server crashing. An attacker can send a crafted URI to trigger this vulnerability.

A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones.
