Uncaught Exception

A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job.Show less

SurrealDB versions before 3.1.0 contain a denial of service vulnerability in the RPC use handler that panics when db is set without a namespace. Unauthenticated attackers can send a malformed WebSocket message to the /rpc endpoint to crash the server process.Show less

SurrealDB versions before 2.2.2 contain an uncaught exception vulnerability in the net module that allows authenticated users to crash the database. Attackers can send crafted HTTP queries containing null bytes to the /sql endpoint, causing an unhandled exception that crashes the SurrealDB instance and any dependent applications.Show less

SurrealDB versions before 1.1.1 fail to properly validate invocation of custom parameters and functions at root or namespace levels, causing server panic. Authorized clients can invoke these entities at unsupported levels to crash the SurrealDB server, resulting in denial of service.Show less

SurrealDB versions before 1.1.0 fail to properly parse the ID, DB, and NS headers in HTTP REST API requests containing special characters. Unauthenticated attackers can send crafted HTTP requests with malformed header values to trigger an uncaught exception that crashes the server.Show less

SurrealDB versions before 1.2.0 contain an uncaught exception vulnerability in the query executor when processing calls to nonexistent built-in functions. Authorized clients can craft pre-parsed queries invoking nonexistent functions to trigger a panic that crashes the server.Show less

SurrealDB versions before 1.2.1 contain an uncaught exception handling vulnerability in span rendering when parsing queries with errors on line terminator characters. Authorized clients can submit malformed queries that trigger a panic in the span rendering code, crashing the server and causing denial of service.Show less

SurrealDB versions before 2.0.4 contain an uncaught exception handling vulnerability in the parser error rendering code when processing empty strings. Authorized clients can execute malformed queries with empty string conversions to record, duration, or datetime types that cause a panic in error rendering, crashing the server.Show less

SurrealDB versions before 2.1.0 contain a denial of service vulnerability in the sorting mechanism when using ORDER BY rand() clause. Authorized clients can execute queries with ORDER BY rand() to trigger a panic in the sorting function, crashing the server.Show less

SurrealDB versions before 2.1.0 contain a denial of service vulnerability in role conversion that allows privileged owner users to define users with nonexistent roles. Attackers can trigger an uncaught panic by signing in with a user assigned an invalid role, crashing the server.Show less

SurrealDB versions before 2.1.0 contain an uncaught exception vulnerability in the rand::time() function that panics when unwrap is called on a None result from timestamp_opt. Authorized clients can repeatedly invoke rand::time() to reliably trigger server panics and cause denial of service.Show less

CoreDNS is a DNS server written in Go. From 1.9.4 until 1.14.5, a network DNS client allowed to request AXFR for a CoreDNS zone can trigger a panic when CoreDNS is configured with k8s_external headless-service zone transfers and Kubernetes contains a headless service endpoint with no declared ports; plugin/kubernetes/object/endpoint.go creates Port: -1, plugin/k8s_external/msg_to_dns.go skips that service, plugin/k8s_external/transfer.go sends an empty []dns.RR batch, and plugin/transfer/transfer.go indexes records[0] without checking the batch is non-empty. This issue is fixed in version 1.14.5.Show less

@grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming compressed message can cause a client or server process that uses @grpc/grpc-js to crash. This issue is fixed in versions 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4.Show less

@grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming HTTP/2 stream initiation can cause a server process created using @grpc/grpc-js to crash. This issue is fixed in versions 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4.Show less

joi is a schema description language and data validator for JavaScript. Prior to 17.13.4 and 18.2.1, denial of service is possible via an untrapped exception in services validating user-supplied JSON or object input with recursive link() schemas. When validate() is called without try/catch in a request handler, deeply nested input can trigger an unhandled RangeError and potentially crash the process; lower-impact paths using validateAsync() or try/catch produce a RangeError instead of a structured ValidationError. This issue is fixed in versions 17.13.4 and 18.2.1.Show less

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, Excelize parses shared-string cell values with strconv.Atoi and checks only the upper bound before indexing the shared string slice, allowing an XLSX file containing a shared-string cell with -1 to trigger sharedStrings[-1] and panic when read through GetCellValue or GetRows. This issue is fixed in version 2.11.0.Show less

NanaZip is the 7-Zip derivative intended for the modern Windows experience. Prior to 6.5.1749.0, NanaZip's .NET single-file bundle handler in NanaZip.Codecs.Archive.DotNetSingleFile.cpp sizes its extraction buffer from the bundle entry Size field, which is only checked for sign and is not validated against the real file size. A crafted bundle can cause an attacker-chosen allocation inside Extract, where std::bad_alloc or std::length_error can escape across the COM STDMETHODCALLTYPE boundary and crash the process. This issue is fixed in version 6.5.1749.0.Show less

CoreWCF is a port of the service side of Windows Communication Foundation (WCF) to .NET Core. Prior to 1.8.1 and 1.9.1, a CoreWCF service listening on a Kafka topic stops processing new records from that topic when KafkaTransportPump receives a null-value tombstone record, causing a persistent endpoint denial of service for attackers with produce permission. This issue is fixed in versions 1.8.1 and 1.9.1.Show less
