Vulnerabilities: 3
Integer underflow in the unlzw function in unlzw.c in gzip before 1.4 on 64-bit platforms, as used in ncompress and probably others, allows remote attackers 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.
The decompress function in compress42.c in (1) ncompress 4.2.4 and (2) liblzw allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code, via crafted data that leads to a buffer underflow.
Stack-based buffer overflow in the comprexx function for ncompress 4.2.4 and earlier, when used in situations that cross security boundaries (such as FTP server), may allow remote attackers to execute arbitrary code via a long filename argument.
