An attacker can cause a crash or denial of service by providing a crafted scanline DWAA file that triggers an integer overflow, resulting in a heap out-of-bounds write duri...

Linux Distros Unpatched Vulnerability : CVE-2025-59731

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - When decoding an OpenEXR file that uses DWAA or DWAB compression, the specified raw length of run-length- encoded data is not checked when using it to calculate...

CVE-2025-59733

When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that all image channels have the same pixel type and size, and that if there are four channels, the first four are "B", "G", "R" and "A". The channel parsing code can be found in decodeheader. The...

DEBIAN-CVE-2025-59732

When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that the height and width are divisible by 8. If the height or width of the image is not divisible by 8, the copy loops at 0 and 1 will continue to write until the next multiple of 8. The buffer...
