What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Avoid importing uncompressed DDS images from untrusted sources. No application-level mitigation that preserves processing of untrusted DDS files is known.

Original source description

Read the full publisher description

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.
