The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1792628290 advisory.

  - An issue in Academy Software Foundation openexr v.3.2.3 and before allows a local attacker to cause a     denial of service (DoS) via the convert function of exrmultipart.cpp. (CVE-2024-31047)

  - 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. This issue has been fixed     in versions 3.2.10, 3.3.12 and 3.4.13. (CVE-2026-55059)

  - 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 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. This     issue has been fixed in versions 3.2.10, 3.3.12, and 3.4.13. (CVE-2026-55373)

  - 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.
