NVD description

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.

    CVE-2010-0001 | When arithmetic points outside the box Imagine a picker sent to a shelf number that does not exist. An integer underflow in gzip's LZW handling could similarly produce an invalid array index on 64-bit systems. A crafted compressed archive could crash the application and possibly allow arbitrary code execution. The issue affected gzip before 1.4, as used in ncompress and potentially other software. The lesson: numbers from untrusted files need bounds checks before they become memory addresses.

    The issue affected gzip before 1.4 and related use in ncompress. A crafted LZW-compressed archive was the trigger. This was not a claim that all compressed files are unsafe. Lesson: check numeric bounds before indexing. Official record: https://github.com/CVEProject/cvelistV5/blob/main/cves/2010/0xxx/CVE-2010-0001.json
