OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.1.0 through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, an int32_t multiplication in OpenEXRCore's unpack_sample_table() can overflow while decoding a crafted deep tiled EXR file, producing an invalid pointer that leads to a read from an unmapped memory address and a crash. Because the overflow occurs in the standard decoding path (exr_decoding_run), any application that decodes deep tiled EXR files is affected. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1792627161 advisory.

  - OpenEXR is the reference implementation and specification for the EXR image format, widely used in the     motion picture industry. In versions 3.4.0 through 3.4.12, a reachable assertion failure in the HTJ2K     decode path allows a crafted HTJ2K-compressed EXR file to cause an unconditional process abort in any     application that calls exr_start_read() on untrusted input, resulting in denial of service. The crash is     triggered by a QCD marker whose lower five bits are zero, which OpenEXR passes into the vendored OpenJPH     library while constructing the codestream and evaluating its quantization delta parameters. OpenJPH uses     an assertion rather than a recoverable error to validate those bits, so any invalid value calls abort()     directly and cannot be intercepted by surrounding error handling, a problem compounded by OpenEXR wrapping     only its internal HT header parser in error handling while leaving the later codestream read and     construction calls unprotected. This issue has been resolved in version 3.4.13. (CVE-2026-54920)

  - OpenEXR is the reference implementation and specification for the EXR image format, widely used in the     motion picture industry. Versions prior to 3.2.10, 3.3.12 and 3.4.13 contain a heap out-of-bounds write in     Imf_4_0::SampleCountChannel::set(int r, unsigned int newNumSamples[]). The row-based sample-count setter     computes the target Y coordinate with dataWindow.min.x instead of dataWindow.min.y. For a valid deep image     data window where min.x != min.y, a valid row index can be translated into an invalid Y coordinate,     causing writes before the allocated _numSamples buffer. The vulnerability is reachable through the public     OpenEXRUtil DeepImage API and can lead to heap corruption and process crashes.

Versions prior to 3.2.10, 3.3.12, and 3.4.13 contain an infinite-loop     vulnerability in SampleCountChannel. The helper roundListSizeUp() rounds a sample-list size up to the next     power of two using repeated unsigned left shifts, which terminates for normal values but fails for     UINT_MAX: the sequence reaches 0x80000000, and the next left shift wraps the 32-bit value to 0. Because 0     remains less than UINT_MAX, the loop never progresses and never exits. The bug is reachable through public     OpenEXRUtil APIs, either by editing the sample-count buffer through SampleCountChannel::Edit (whose     destructor calls endEdit()) or by calling SampleCountChannel::set(x, y, UINT_MAX) on a valid pixel.

Versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 allow a     crafted EXR with a nonzero dataWindow.min to make TypedFlatImageChannel::row() return an invalid heap     pointer, causing out-of-bounds or use-after-free writes. This occurs when an application writes rows     through FlatHalfChannel::row(). Affected consumers are tools, converters, render pipeline components, or     image-processing services that accept untrusted EXR files and use FlatHalfChannel::row() on loaded images.

    OpenEXR is the reference implementation and specification for the EXR image format, widely used in the     motion picture industry. In OpenEXRUtil versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.12, the     documented TypedDeepImageChannel<T>::row() 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. The flaw arises because ImfDeepImageChannel uses two     conflicting coordinate models: at(x, y) uses absolute coordinates (with _base offset by dataWindow.min),     while row(r) is documented as 0-based logical access. For a non-zero dataWindow.min, row(0) therefore     points outside the _sampleListPointers allocation instead of at the first logical row. This issue is fixed     in versions 3.3.13 and 3.4.13. (CVE-2026-59189)

    OpenEXR is the reference implementation and specification for the EXR image file format, widely used in     the motion picture industry. In versions through 3.2.10, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13,     the OpenEXRUtil library returns an out-of-bounds pointer from the SampleCountChannel::row() API when a     deep image has a non-zero dataWindow origin. The row() accessor is documented as 0-based and computes its     address from an internal base that is offset for absolute pixel coordinates, so the two coordinate models     conflict whenever dataWindow.min is non-zero. For a deep image whose data window has a large negative     vertical origin, row(0) points far outside the allocated sample-count buffer. An application that opens an     attacker-controlled deep EXR file and accesses 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. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14. (CVE-2026-59981)

OpenEXR versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13     can return an out-of-bounds pointer from TypedDeepImageChannel::row() when a crafted deep EXR has a     nonzero dataWindow origin. This vulnerability occurs because the API combines zero-based row access with     an absolute-coordinate-adjusted base pointer, allowing a crash or limited information disclosure. This     issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14. (CVE-2026-59982)

OpenEXR versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13     are vulnerable to crashing. This 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. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14. (CVE-2026-61555)

    OpenEXR is the reference implementation and specification for the EXR image format, widely used in the     motion picture industry. In versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13,     exrmultiview can write past a heap allocation when it combines two attacker-supplied, individually valid     scanline EXR files whose union dataWindow is not aligned to one view's channel subsampling. 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. The trigger is     normal public-tool processing, such as exrmultiview left A.exr right B.exr out.exr with crafted but valid     inputs, so this is not solely an API or caller-precondition issue. This issue is fixed in versions 3.2.11,     3.3.13, and 3.4.14. (CVE-2026-68515)
