Doc Text:
A flaw was found in schroedinger. By tricking a user or application into processing a specially crafted Dirac video stream, an attacker can trigger a division-by-zero condition during the parsing of low-delay transform parameters. This failure causes the application to crash unexpectedly, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-18 12:42:06 UTC
Schroedinger libschroedinger through 1.0.11 contains a divide by zero vulnerability that allows attackers to crash applications by supplying a zero slice_bytes_denom or slice count in a Dirac stream. Attackers can provide a crafted low-delay picture parsed by schro_decoder_parse_transform_parameters and schro_decoder_parse_lowdelay_transform_data to trigger a SIGFPE and cause denial of service.
