This update for openexr fixes the following issues:

• CVE-2026-59184: invalid heap pointer, causing out-of-bounds or use-after-free writes (bsc#1276849).
• CVE-2026-59186: On ILP32, the Array2D tile-conversion buffer size calculation overflows, allocates a much smaller heap buffer, and tile decode writes past that allocation (bsc#1276850).
• CVE-2026-59189: API can return an out-of-bounds pointer when a deep image has a non-zero dataWindow origin, resulting in a heap out-of-bounds read and crash, with potential information disclosure under a controlled heap layout (bsc#1276855).
• CVE-2026-59981: an attacker-controlled deep EXR file can access sample counts through row() performs an out-of-bounds read, which can crash the process or, under a controlled heap layout, return adjacent heap memory as sample-count values (bsc#1276862).
• CVE-2026-59982: an out-of-bounds pointer from TypedDeepImageChannel::row() when a crafted deep EXR has a nonzero dataWindow origin (bsc#1276853).
• 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).
