An update that solves three vulnerabilities can now be installed.

## Description:

This update for openexr fixes the following issues:

  * CVE-2026-59186: On ILP32, the Array2D<Rgba> tile-conversion buffer size
    calculation overflows, allocates a much smaller heap buffer, and tile decode
    writes past that allocation (bsc#1276850).
  * CVE-2026-61555: crashing occurs when Imf::GetChannelsInMultiPartFile()
    processes a crafted EXR with an empty multiView header attribute and
    Imf::viewFromChannelName() indexes the empty vector for a dotless channel
    name (bsc#1276859).
  * CVE-2026-68515: The utility allocates sampled channel storage using a
    truncated union_width / xSampling, then reads the sampled input through a
    Slice based on the misaligned union window, producing a heap out-of-bounds
    write (bsc#1276848).
