Integer underflow in the unlzw function in unlzw.c in gzip prior to 1.4 on 64-bit platforms, as used in ncompress and probably others, allows remote malicious users to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted archive that uses LZW compression, leading to an array index error.
