CVE-2026-96546
Gimp: gimp: one-byte out-of-bounds heap read in the uncompressed dds loader
A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated.
Fixes and workarounds
Workaround
Avoid importing uncompressed DDS images from untrusted sources. No application-level mitigation that preserves processing of untrusted DDS files is known.
