• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-369

Description

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.
