Summary

FFmpeg 0.10 through 9.0.2 contains a use of uninitialized resource vulnerability in sunrast_decode_frame() that leaks heap memory when decoding truncated 1-bit and 4-bit paletted Sun Raster images. A crafted truncated Sun Raster file can cause the uncleared temporary bitmap to be expanded into PAL8 pixels, exposing stale heap contents.

Risk Assessment

An attacker may expose heap memory contents in the decoded image. This can lead to leakage of sensitive information from the image processing process.

Recommendation

Update FFmpeg to a version that contains the fix. Until then, avoid decoding untrusted Sun Raster files.

Original NVD description (English source)

FFmpeg 0.10 through 9.0.2 contains a use of uninitialized resource vulnerability in sunrast_decode_frame() that leaks heap memory when decoding truncated 1-bit and 4-bit paletted Sun Raster images. Attackers can craft a truncated Sun Raster file so the uncleared temporary bitmap is expanded into PAL8 pixels, exposing stale heap contents such as allocator words in decoded output.
