"Several vulnerabilities have been found in gzip, the GNU compression
utilities. The Common Vulnerabilities and Exposures project identifies
the following problems :

  - CVE-2009-2624
    Thiemo Nagel discovered a missing input sanitation flaw
    in the way gzip used to decompress data blocks for
    dynamic Huffman codes, which could lead to the execution
    of arbitrary code when trying to decompress a crafted
    archive. This issue is a reappearance of CVE-2006-4334
    and only affects the lenny version.

  - CVE-2010-0001
    Aki Helin discovered an integer underflow when
    decompressing files that are compressed using the LZW
    algorithm. This could lead to the execution of arbitrary
    code when trying to decompress a crafted LZW compressed
    gzip archive."
