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-2026-61720 FluidSynth: SF2 DMOD Chunk Unsigned Underflow

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...

EUVD-2026-83378

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...

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...

CVE-2026-61723

FluidSynth (a software synthesizer based on the SoundFont 2 specifications) versions 2.5.0 through 2.5.6 are affected by an integer overflow in the native DLS parser's ptbl chunk validation. The expression cues * 4 + cbsize uses 32-bit unsigned arithmetic without bounds checking; with cues = 0x40...

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...

CVE-2026-77396

PJSIP is a free and open source multimedia communication library written in C. In 2.17 and earlier, the PJSIP AVI parser in pjmedia/src/pjmedia/aviplayer.c uses an input-file video chunk length as the number of bytes copied into a frame buffer whose capacity is derived from the declared media...
