DEBIAN-CVE-2026-71418

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, DNS-over-HTTP/2 processing in rust/src/http2/http2.rs retains previously processed HTTP/2 DATA frame contents instead of clearing the internal buffer...

DEBIAN-CVE-2026-75895

In libsmpp35 from 0.1.0 through 1.8.0 out of bound read issue was found in the at smpp34unpack function via attacker controlled SMPP PDUs, leading to memory corruption...

DEBIAN-CVE-2026-58264

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 1.1.2 until 2.5.6, the FluidSynth command handler accepts a pitchbendrange command whose channel argument is not bounds checked before the supplied value is written through the selected synth channel. An out-of-ran...

DEBIAN-CVE-2026-61722

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates articulation chunks using the unsigned expression cbsize + connblocks 12 without first ensuring that the multiplication and addition fit in 32 bits. A crafted DLS...

DEBIAN-CVE-2026-61714

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.2.4 until 2.5.6, configuring synth.midi-channels above 16 allows the MIDI player to index fluidplayert::channelisplaying outside its fixed-size heap allocation while tracking active channels. The resulting...

DEBIAN-CVE-2026-61723

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates ptbl chunks with the unsigned expression cues 4 + cbsize without checking whether the multiplication and addition fit in 32 bits. A crafted DLS file can supply a...

DEBIAN-CVE-2026-61721

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS loader assigns file-controlled wsmp.loopstart and wsmp.looplength values to samples without calling fluidsamplevalidate or fluidsamplesanitizeloop. A crafted DLS file can place...

DEBIAN-CVE-2026-61720

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the SF2 parser computes the DMOD modulator count as chunk.size / SFMODSIZE - 1 without rejecting chunks smaller than one record. A crafted SF2 file containing a zero-sized DMOD chunk makes the...

DEBIAN-CVE-2026-69186

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsparse trusts the attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT fields before confirming that the DNS response contains enough bytes for the claimed records. Because processanswer invokes parsing before transaction ID and...

DEBIAN-CVE-2026-69184

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsnameparse enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource...

DEBIAN-CVE-2026-61552

Icinga 2 is an open source monitoring system. From 2.4 until 2.14.9, 2.15.4, and 2.16.2, the /v1/objects API writes attacker-controlled template names into generated configuration without escaping them. An authenticated ApiUser with an objects/create/ permission can inject Icinga 2 DSL...

DEBIAN-CVE-2026-61551

Icinga 2 is an open source monitoring system. Prior to 2.14.9, 2.15.4, and 2.16.2, parsing deeply nested JSON can exhaust the call stack because nesting depth is not bounded. The affected JSON parsing paths are reachable by unauthenticated network clients through the Icinga 2 service on TCP port...

DEBIAN-CVE-2026-61550

Icinga 2 is an open source monitoring system. From 2.8 until 2.14.9, 2.15.4, and 2.16.2, certificate update JSON-RPC message handling does not validate that the sender is a trusted endpoint. An unauthenticated network attacker able to connect to TCP port 5665 can replace the node certificate and...

DEBIAN-CVE-2026-91149

A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the cockpit-tls service. This forces the service to create an unbounded number of detached threads, consuming system resources such as...

DEBIAN-CVE-2026-61548

Rsyslog is a rocket-fast system for log processing. From 7.5.4 until 8.2606.0, the optional mmpstrucdata plugin's parseSDPARAM function in plugins/mmpstrucdata/mmpstrucdata.c stores RFC5424 parameter values in a fixed pVal32 1024 stack buffer and calls parsePARAMVALUE without supplying the...

DEBIAN-CVE-2026-55556

Rsyslog is a rocket-fast system for log processing. From 8.2110.0 until 8.2604.0, the optional imhttp module's parseauthheader function in contrib/imhttp/imhttp.c allocates a zero-byte heap buffer with calloc0, len when an HTTP Basic Authorization value exceeds its fixed work buffer, then passes...
