libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. Versions 1.8.7 and prior contain a Use-After-Free vulnerability via the loadgif function in fromgif.c, where a single sixelframet object is reused across all frames of an animated GIF and gifinitframe unconditionally...

CVE-2026-33018

libsixel 1.8.7 and prior contain a heap use‑after‑free in load_gif() (fromgif.c): a single sixel_frame_t is reused across all frames of an animated GIF and gif_init_frame() frees/reallocates frame->pixels between frames regardless of reference counts. A callback using sixel_frame_get_pixels() ...

netty: Netty: Denial of Service via HTTP/2 CONTINUATION frame flood

A flaw was found in Netty. A remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume...

undici: undici: Denial of Service via crafted WebSocket frame with large length

A flaw was found in undici. A remote attacker could exploit this vulnerability by sending a specially crafted WebSocket frame with an extremely large 64-bit length. This causes undici's ByteParser to overflow its internal calculations, leading to an invalid state and a fatal TypeError. The primar...
