An issue was discovered in FNET through 4.6.4. The code for IPv6 fragment reassembly tries to access a previous fragment starting from a network incoming fragment that still doesn't have a reference to the previous one (which supposedly resides in the reassembly list). When faced with an incoming fragment that belongs to a non-empty fragment list, IPv6 reassembly must check that there are no empty holes between the fragments: this leads to an uninitialized pointer dereference in _fnet_ip6_reassembly in fnet_ip6.c, and causes Denial-of-Service.
An issue was discovered in FNET through 4.6.4. The code for processing resource records in mDNS queries doesn't check for proper '\0' termination of the resource record name string, leading to an out-of-bounds read, and potentially causing information leak or Denial-or-Service.
An issue was discovered in FNET through 4.6.4. The code for processing the hostname from an LLMNR request doesn't check for '\0' termination. Therefore, the deduced length of the hostname doesn't reflect the correct length of the actual data. This may lead to Information Disclosure in _fnet_llmnr_poll in fnet_llmnr.c during a response to a malicious request of the DNS class IN.

BACnet Protocol Stack library provides a BACnet application layer, network layer and media access (MAC) layer communications services. Prior to 1.5.0.rc2, The npdu_is_expected_reply function in src/bacnet/npdu.c indexes request_pdu[offset+2/3/5] and reply_pdu[offset+1/2/4] without verifying that those APDU bytes exist. bacnet_npdu_decode() can return offset == 2 for a 2-byte NPDU, so tiny PDUs pass the version check and then get read out of bounds. On ASan/MPU/strict builds this is an immediate crash (DoS). On unprotected builds it is undefined behavior and can mis-route replies; RCE is unlikely because only reads occur, but DoS is reliable.
A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association, a PFCP Session Establishment Request that includes a CreateFAR with an empty or truncated IPv4 address field is not properly validated. During parsing, parseFAR() calls ip2int(), which performs an out-of-bounds read on the IPv4 address buffer and triggers an index-out-of-range panic. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF and disrupt user-plane services.
An issue was discovered in the lazy-init crate through 2021-01-17 for Rust. Lazy lacks a Send bound, leading to a data race.
An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
A denial-of-service vulnerability exists in the omec-project UPF (pfcpiface component) in version upf-epc-pfcpiface:2.1.3-dev. After PFCP association, a specially crafted PFCP Session Establishment Request with a CreatePDR that contains a malformed Flow-Description is not robustly validated. The Flow-Description parser (parseFlowDesc) can read beyond the bounds of the provided buffer, causing a panic and terminating the UPF process. An attacker who can send PFCP Session Establishment Request messages to the UPF's N4/PFCP endpoint can exploit this issue to repeatedly crash the UPF.
XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences. A node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory. Any Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service.
sipclient.cpp in KPhone 4.0.1 and earlier allows remote attackers to cause a denial of service (crash) via a STUN response packet with a large attrLen value that causes an out-of-bounds read.
A vulnerability was detected in Open5GS up to 2.7.7. This affects the function ogs_sbi_client_send_via_scp_or_sepp in the library lib/sbi/client.c of the component NF. Performing a manipulation results in out-of-bounds read. The attack is possible to be carried out remotely. The patch is named d5bc487fcf9ea87d2b03f2ef95123af344773bfb. It is suggested to install a patch to address this issue.
An out-of-bounds read in the header_cmp function (mk_server/mk_http_parser.c) of monkey commit f37e984 allows attackers to cause a Denial of Service (DoS) via sending a crafted HTTP request to the server.

Missing bounds validation in the MQTT v5.0 property parser in coreMQTT before 5.0.1 allows an MQTT broker to cause a denial of service by sending a crafted packet. To remediate this issue, users should upgrade to v5.0.1.
An out-of-bounds read in the mk_mimetype_find function (mk_server/mk_mimetype.c) of monkey commit f37e984 allows attackers to cause a Denial of Service (DoS) via sending a crafted HTTP request to the server.
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the metaphone() function in ext/standard/metaphone.c uses a signed int variable to track the current position within the input string. If a string longer than 2,147,483,647 bytes is passed, a signed integer overflow occurs, resulting in undefined behavior. This can lead to an out-of-bounds read, causing a segmentation fault or access to unrelated memory, and may affect the availability of the PHP process.
An out-of-bounds read in the http_parser_transfer_encoding_chunked function (mk_server/mk_http_parser.c) of monkey commit f37e984 allows attackers to cause a Denial of Service (DoS) via sending a crafted POST request to the server.
Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). ParticipantGenericMessage is the DDS Security control-message container that carries not only the handshake but also on going security-control traffic after the handshake, such as crypto-token exchange, rekeying, re-authentication, and token delivery for newly appearing endpoints. On receive, the CDR parser is invoked first and deserializes the `message_data` (i .e., the `DataHolderSeq`) via the `readParticipantGenericMessage → readDataHolderSeq` path. The `DataHolderSeq` is parsed sequentially: a sequence count (`uint32`), and for each DataHolder the `class_id` string (e.g. `DDS:Auth:PKI-DH:1.0+Req`), string properties (a sequence of key/value pairs), and binary properties (a name plus an octet-vector). The parser operat es at a stateless level and does not know higher-layer state (for example, whether the handshake has already completed), s o it fully unfolds the structure before distinguishing legitimate from malformed traffic. Because RTPS permits duplicates, delays, and retransmissions, a receiver must perform at least minimal structural parsing to check identity and sequence n umbers before discarding or processing a message; the current implementation, however, does not "peek" only at a minimal header and instead parses the entire `DataHolderSeq`. As a result, prior to versions 3.4.1, 3.3.1, and 2.6.11, this parsi ng behavior can trigger an out-of-memory condition and remotely terminate the process. Versions 3.4.1, 3.3.1, and 2.6.11 p atch the issue.
Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. This issue may occur when a Datagram Transport Layer Security (DTLS) 1.2 virtual server is enabled with a Server SSL profile that is configured with a certificate, key, and the SSL Sign Hash set to ANY, and the backend server is enabled with DTLS 1.2 and client authentication. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A vulnerability was identified in osrg GoBGP up to 4.3.0. Affected by this issue is the function BMPPeerUpNotification.ParseBody/BMPStatisticsReport.ParseBody of the file pkg/packet/bmp/bmp.go of the component BMP Parser. The manipulation leads to out-of-bounds read. The attack can be initiated remotely. Upgrading to version 4.4.0 can resolve this issue. The identifier of the patch is bc77597d42335c78464bc8e15a471d887bbdf260. Upgrading the affected component is recommended.
The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function.
In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, some functions, including urldecode(), pass signed char to ctype functions (like isxdigit()). On the systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can lead to accessing array with negative offset, which can trigger a denial of service.
When a BIG-IP APM OAuth access profile (Resource Server or Resource Client) is configured on a virtual server, undisclosed traffic can cause the apmd process to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
In NextX Duo before 6.4.4, in the HTTP client module, the network support code for Eclipse Foundation ThreadX, the parsing of HTTP header fields was missing bounds verification. A crafted server response could cause undefined behavior.
TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, source/libs/transport/src/transComm.c transDecompressMsg() read STransCompMsg.contLen when pHead->comp == 1 without first validating that the RPC packet contained the 8-byte STransCompMsg structure, causing an unauthenticated out-of-bounds read, uncontrolled allocation, integer underflow, and server crash. This issue is fixed in version 3.4.1.15.
A flaw was found in privoxy before 3.0.32. A invalid read of size two may occur in chunked_body_is_complete() leading to denial of service.
Possible buffer over read due to improper validation of frame length while processing AEAD decryption during ASSOC response in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon IoT, Snapdragon Mobile, Snapdragon Voice & Music
Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.3, Oj::Doc#each_child, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process, leading to DoS. In a two-step chain in ext/oj/fast.c, doc_each_child increments doc->where past the where_path[MAX_STACK = 100] array with no bounds check and never restores it (the doc->where-- is missing), so calling each_child recursively from inside the yield block drives doc->where beyond the array. On the next entry the function copies the path into the 800-byte stack-local buffer save_path[MAX_STACK] using wlen = doc->where - doc->where_path, so when the previous recursive call left doc->where past where_path[100] the wlen exceeds MAX_STACK and the memcpy overflows save_path on the C stack; because the Oj::Doc parser imposes no JSON nesting-depth limit (relying on a C-stack pressure check), deeply nested attacker input reaches this path. This issue has been fixed in version 3.17.3.
A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability.
