EUVD-2026-83387
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 8.0.6, the FTP parser in src/app-layer-ftp.c treats a RETR or STOR command sent before PORT or PASV negotiation as a fatal application-layer error instead of a recoverabl...
CVE-2026-63450 Suricata ftp: RETR/STOR before PORT/PASV can disable further IDS app-layer detection
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 8.0.6, the FTP parser in src/app-layer-ftp.c treats a RETR or STOR command sent before PORT or PASV negotiation as a fatal application-layer error instead of a recoverabl...
CVE-2026-63450
The Suricata network Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) is vulnerable in versions prior to 8.0.6 due to a flaw in the FTP parser located in src/app-layer-ftp.c. The parser incorrectly treats a RETR or STOR command sent before PORT or PASV negotiation as a fatal...

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the...
CVE-2026-63449
Suricata versions 8.0.0 through 8.0.6 are vulnerable to a flaw in the SIP parser (specifically in rust/src/sip/parser.rs). The parser incorrectly uses 16-bit fields to store request and response body lengths. Consequently, a SIP body exceeding 65,536 bytes causes the length to truncate, preventin...
CVE-2026-63449 Suricata sip: large SIP message bodies can evade detection with frame keyword
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the...

CVE-2026-57224
Suricata versions 8.0.0 through 8.0.6 are affected by a denial-of-service vulnerability in the DHCP parser (rust/src/dhcp/dhcp.rs) and RDP parser (rust/src/rdp/rdp.rs). Both parsers create stateless transactions without recording packet direction via AppLayerTxData::for_direction(). When a sensor...
CVE-2026-57224 Suricata dhcp: unbounded transactions in unidirectional traffic can lead to resource exhaustion
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the DHCP parser in rust/src/dhcp/dhcp.rs creates stateless transactions without recording their packet direction with AppLayerTxData::fordirection, so a...

CVE-2026-61720
FluidSynth, a software synthesizer based on the SoundFont 2 specification, is affected by an unsigned integer underflow in its SF2 parser's DMOD chunk handler. When a crafted SF2 file contains a zero-sized DMOD chunk, the expression chunk.size / SF_MOD_SIZE - 1 causes the unsigned subtraction to ...
CVE-2026-61723 FluidSynth: DLS ptbl Chunk Integer Overflow
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...
