Summary: Security update for openexr

Details: 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).
