Bump openexr from 3.3.5 to 3.4.4

Open dependabot[bot] opened this issue 1 month ago • 0 comments

Bumps openexr from 3.3.5 to 3.4.4.

Release notes

Sourced from openexr's releases.

v3.4.4

Patch release with an optimization to reduce the size of the library.

B44 and DWA compression tables are now initialized at first use rather than being hard-coded in the source code and compiled binary. This reduces the library size at a slight performance cost. Initialization takes under a millisecond, but the size of libOpenEXRCore.so is reduced from around 1Mb to less than half that.

This also fixes a build issue with ILMTHREAD_THREADING_ENABLED which inadvertently enabled threading when it should have been disabled.

This also fixes a bug where importing the python module from a parent directory would fail.

Full changelog: v3.4.3..v3.4.4

v3.4.3

Patch release that addresses several bugs, primarily involving properly rejecting corrupt input data.

Specifically:

  • Buffer overflow in PyOpenEXR_old's channels() and channel() in legacy python, reported by Joshua Rogers (GitHub: MegaManSec).
  • Use after free in PyObject_StealAttrString in legacy python, reported by Joshua Rogers (GitHub: MegaManSec).
  • Use of Uninitialized Memory in openexr, reported by Aldo Ristori (GitHub: Kaldreic).
  • Heap-based Buffer Overflow Remote Code Execution Vulnerability, reported by Trend Micro Zero Day Initiative.

Also:

  • OSS-fuzz 456158449 Heap-buffer-overflow in generic_unpack
  • OSS-fuzz 447429458 Heap-buffer-overflow in DwaCompressor_uncompress
  • OSS-fuzz 439237843 Heap-buffer-overflow in internal_exr_undo_ht
  • OSS-fuzz 436037111 Heap-buffer-overflow in generic_unpack
  • OSS-fuzz 435779241 Heap-buffer-overflow in generic_unpack
  • OSS-fuzz 420744464 Abrt in __cxxabiv1::failed_throw

Other fixes:

  • Fix a bug with re-reading a scanline file with a different set of channels.
  • Only populate CMAKE_DEBUG_POSTFIX with _d if it is undefined, which makes it possible to set CMAKE_DEBUG_POSTFIX="".

This version also bumps the auto-fetched version of OpenJPH to 0.24.5. OpenJPH 0.24.5 addresses these OSS-Fuzz issues:

  • OSS-fuzz 456837230 Crash in ojph::local::param_cod::~param_cod
  • OSS-fuzz 456248580 Null-dereference READ in ojph::local::param_cod::~param_cod
  • OSS-fuzz 455374208 Floating-point-exception in ojph::local::tile::pre_alloc
  • OSS-fuzz 444963190 Index-out-of-bounds in ojph::local::param_qcd::read_qcc
  • OSS-fuzz 444889300 Heap-buffer-overflow in ojph::mem_infile::read
  • OSS-fuzz 444878558 Segv on unknown address in ojph::local::param_qcd::~param_qcd
  • OSS-fuzz 444878557 Null-dereference READ in ojph::local::param_qcd::~param_qcd

Full changelog: v3.4.2..v3.4.3

v3.4.2

Patch release that fixes a Windows build issue introduced in v3.4.1.

This version also bumps the auto-fetched Imath version to v3.2.2, which resolves a build problem with newer versions of cmake, involving duplicate library aliases.

Version 3.4.4 (November 19, 2025)

Patch release with an optimization to reduce the size of the library.

B44 and DWA compression tables are now initialized at first use rather than being hard-coded in the source code and compiled binary. This reduces the library size at a slight performance cost. Initialization takes under a millisecond, but the size of libOpenEXRCore.so is reduced from 890K to 360K.

This also fixes a build issue with ILMTHREAD_THREADING_ENABLED which inadvertently enabled threading when it should have been disabed.

This also fixes a bug where importing the python module from a parent directory would fail.
