| Summary | The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow. |

| Title | LibTIFF の tiff2pdf におけるサービス運用妨害 (クラッシュ) の脆弱性 |
|---|---|
| Summary | LibTIFF の tiff2pdf (tools/tiff2pdf.c) 内の t2p_read_tiff_init 関数は、特定のエラーが発生する状況において、T2P コンテキストの構造体ポインタを適切に初期化しないため、サービス運用妨害 (クラッシュ) 状態となる、および任意のコードを実行される脆弱性が存在します。 |
| Possible impacts | 攻撃者により、ヒープベースのバッファオーバーフローを誘発する巧妙に細工された TIFF 画像を介して、サービス運用妨害 (クラッシュ) 状態にされる、および任意のコードを実行される可能性があります。 |
| Solution | ベンダ情報および参考情報を参照して適切な対策を実施してください。 |
