The vulnerability of the Box_stts::get_sample_duration() function in the HEIF and AVIF file encoding/decoding library allows a perpetrator to trigger a service failure.

The vulnerability of the Boxstts::getsampleduration function in the HEIF and AVIF file encoding/decoding library lies in the execution of a loop with an unreachable exit condition. Exploiting this vulnerability could allow a malicious actor to cause service failures...

SUSE CVE-2026-32739

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 800-byte HEIF sequence file causes an infinite loop in Boxstts::getsampleduration, consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the getsampleduration function. An attacker can cause the application to enter an infinite loop and consume excessive CPU resources by providing a specially crafted HEIF file during file parsing. Remediation Upgrade...
