Echo: libheif: security update to 1.23.2-1

high Tenable Cloud Security Plugin ID 472770

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - libheif is a HEIF and AVIF file format decoder and encoder. Prior to 1.23.2, crafted HEIF sequence timing
 and edit-list data can make Track::init_sample_timing_table() compute a logical m_num_output_samples value
 that exceeds the uint32_t counters used by Track_Visual::decode_next_image_sample() and
 Track::get_next_sample_raw_data(). The resulting comparison can never reach the oversized output count,
 causing non-terminating decode or raw-sample loops and bypassing max_sequence_frames. The same sequence
 path repeatedly calls Box_stts::get_sample_duration() and allocates Chunk::m_sample_ranges and
 Track::m_presentation_timeline outside MemoryHandle accounting, allowing severe CPU and memory exhaustion
 from a small file. This issue is fixed in version 1.23.2. (CVE-2026-84446)

Solution

Update the libheif library and its related packages to version 1.23.2-1 or later.
